To guarantee sustained innovation and stay at the absolute forefront of industrial power electronics, we dedicate no less than 20% of our annual sales revenue back into research and development.
This aggressive R&D posture supports our specialized technical team, which includes respected doctoral supervisors, senior electrical engineers, and master’s degree researchers. In the last three years alone, Deming successfully executed 17 core R&D projects, directly translating 16 scientific and technological breakthroughs into commercialized, high-reliability products now operating in critical environments worldwide.
Global energy markets are undergoing a fundamental transformation characterized by decarbonization, decentralization, and the digitization of utility networks. As traditional centralized grids struggle to integrate volatile renewable generation, the demand for High-Efficiency Systems has surged. Modern industries require resilient hardware capable of mitigating power fluctuations, stabilizing load flows, and providing seamless grid-interactive support.
Our industrial-grade power electronics address critical challenges in diverse application fields. From port electrification through our Ship Shore Power Systems to stabilizing remote off-grid networks with our high-capacity hybrid solar inverters, we build energy resiliency. High-performance systems reduce operational expenditures (OPEX) by minimizing heat dissipation losses, extending component lifespans, and ensuring strict compliance with local grid codes.
Standard power conversion systems waste significant energy as thermal dissipation. By employing advanced silicon carbide (SiC) or insulated-gate bipolar transistor (IGBT) switches and optimizing magnetic core configurations, Deming’s converters achieve conversion efficiencies up to 99%. This level of efficiency prevents thermal runaway and reduces cooling requirements, which is essential for heavy manufacturing plants, mining complexes, and offshore operations.
How our high-efficiency systems adapt to specialized grid requirements, environmental challenges, and operational profiles worldwide.
Maritime regulations require vessels to shut down diesel auxiliary engines while berthed to reduce emissions. Our Ship Shore Power Systems (500kW to 5MW) isolate shore power from the ship's onboard grid, providing high-efficiency frequency transformation (e.g., 50Hz to 60Hz or vice versa). Designed for saline and highly humid coastal environments, these cabinets feature IP55/NEMA 4X enclosures and advanced liquid-to-air cooling options to ensure uninterrupted operation.
For isolated agricultural operations, remote mining stations, or island grids, diesel generation is expensive and carbon-intensive. By combining our Low RPM Permanent Magnet Generators with Induction Capacitance Mixed Load Solar Inverters, remote regions can construct stable local grids. These controllers balance capacitive and inductive industrial loads dynamically, preventing microgrid voltage collapse during high-inrush motor starts.
As battery gigafactories scale up production, battery test systems require bidirectional energy recycling to save cost. Our 150kW to 500kW Bidirectional DC Power Supplies act as battery simulators, testing battery modules under high charge-discharge cycles. By returning power back to the grid at 99% efficiency during discharge tests, testing facilities drastically lower utility costs and keep local distribution grids clean.
In residential applications in Northern Europe and North America, seasonal variability makes single-source off-grid systems unreliable. The 10KW Hybrid Solar Wind Turbine System provides reliable domestic power by balancing solar PV during the day and wind turbine input during high-wind night cycles. The integrated MPPT algorithm tracks optimal wind blade aerodynamics in real time, increasing annual yield by up to 25%.
Operating within Jinan's industrial manufacturing ecosystem allows Jinan Deming Power Equipment to maintain a highly resilient and reliable supply chain. Our partnerships with raw material suppliers, specialized component foundries, and semiconductor houses ensure that production stays on schedule, even during global supply disruptions. This vertical integration allows us to achieve shorter lead times, rigorous quality checks at every level, and competitive pricing structures without compromising reliability.
Our raw materials—such as high-permeability silicon steel sheets, pure copper bars, and high-coercivity NdFeB magnets—are sourced from audited long-term suppliers. By executing circuit board assembly, high-precision copper bar shaping, transformer winding, thermal debugging, and performance verification in-house, we control the quality of every product that leaves our facility. This ensures reliable operations across the 120+ countries we serve.

Deming's technology roadmap focuses on three main pillars: digital power control, wide-bandgap semiconductor integration, and modular bidirectional topology. As grids shift toward decentralization, our engineering focus targets optimizing power conversion performance.
By transitioning our converters from silicon IGBTs to SiC MOSFETs, we reduce switching energy losses and thermal load. This upgrade supports higher operating temperatures and switching frequencies, leading to more compact systems.
Future converters will incorporate VSM software protocols to emulate virtual rotational inertia. This function helps stabilize grids with high renewable energy penetration, preventing frequency drops during grid disturbances.
Integrating microcontrollers with edge computing allows real-time thermal and mechanical strain monitoring. The system uses these data points to alert operators before component faults occur, helping reduce unplanned downtime.
Selling industrial power equipment globally requires strict adherence to international electrical, safety, and grid connection rules. Deming systems are engineered to meet key international certifications, facilitating smooth approval and deployment processes:
Our engineers work closely with local EPC partners to offer remote debugging support, circuit customization, and custom firmware calibration, ensuring fast integration and commission times.
Get answers to core technical and integration questions regarding our permanent magnet generators, bidirectional converters, and hybrid controllers.
Traditional induction generators require a high input speed and external excitation currents, often needing a gearbox to match high-frequency operation. Gearboxes introduce mechanical wear, thermal losses, and regular maintenance requirements. Deming’s Low RPM Permanent Magnet Generators (PMG) utilize high-grade NdFeB magnets, eliminating excitation losses and enabling high efficiency at lower speeds. This direct-drive configuration removes the need for a gearbox, reducing maintenance costs and improving reliability in wind, hydro, and marine applications.
Our bidirectional DC power supplies utilize high-efficiency topologies, incorporating low-loss silicon carbide (SiC) switching devices and optimized high-frequency magnetic components. The control system uses digital space vector pulse width modulation (SVPWM) to reduce switching losses. When testing energy storage systems, the bidirectional topology recycles energy back to the AC grid with minimal loss, achieving up to 99% conversion efficiency.
Yes. Our Induction Capacitance Mixed Load Solar Power Charge Controllers and Hybrid Inverters are designed to handle inductive loads. They feature high surge handling capability, allowing them to deliver up to three times their rated output during start-up. Built-in reactive power compensation stabilizes voltage during heavy inductive motor starts, preventing system trips or voltage sags.
Our FKJ-GT series wind turbine grid-tie controllers feature multiple protection systems to protect both the turbine and the local grid. These include islanding protection, over-voltage/under-voltage protection, over-frequency/under-frequency detection, and over-current monitoring. The controller also features an automatic dump load control system that diverts excess energy during grid outages or high wind conditions to prevent turbine overspeed.
Our engineering team can customize systems for specific project requirements. We offer adjustments to input voltage ranges, output voltage levels, communication protocols (such as Modbus RTU/TCP, CAN, or Profinet), and enclosures (including custom NEMA/IP ratings and marine-grade coatings for corrosive environments).
