Galvanically isolated modular systems designed for grid-scale stability, BESS configurations, and EV battery testing.
Established in 2004, Jinan Deming Power Equipment Co., Ltd. is a nationally recognized high-tech enterprise dedicated to the design, research, development, and high-efficiency manufacturing of industrial-grade renewable energy power equipment. With nearly two decades of engineering excellence, we specialize in high-power conversion topologies, microgrid optimization systems, and comprehensive power testing solutions.
Our commitment to cutting-edge technology development is backed by a substantial R&D investment structure, directing no less than 20% of annual sales revenue into new technology exploration. Operating with an elite team of 16 research engineers, including doctoral supervisors and master’s degree holders, Deming has successfully finalized 17 major R&D projects in the past three years alone, commercializing 16 direct technological breakthroughs into market-leading products.
Decoupling power dynamics with wide bandgap semiconductors, high-frequency isolation, and digital control loops.
Moving away from traditional silicon IGBTs, our advanced converter architectures selectively utilize Silicon Carbide (SiC) and Gallium Nitride (GaN) MOSFETs. This configuration achieves significantly reduced switching losses, higher operating thermal limits, and allows power density expansion beyond 3kW/L, ensuring stable continuous operations under demanding duty cycles.
Our bidirectional topologies utilize Dual Active Bridge (DAB) and LLC resonant converters with galvanic isolation. By employing high-frequency transformers internally, we guarantee safe isolation barrier protection between battery arrays (200V-1500V) and the common DC bus, eliminating grounding noise and fault-propagation risks.
We deploy high-speed Texas Instruments TMS320 series DSPs paired with rugged FPGA platforms to run real-time control algorithms. Featuring dynamic drop control, phase-shifted modulation, and response time metrics under 2 milliseconds, our converters seamlessly adapt to severe grid load transients without stepping offline.
Optimizing power balancing, microgrid dispatch, and commercial testing applications worldwide.
Acting as the critical interface between battery energy storage systems (BESS) and high-voltage DC networks, our converters facilitate peak shaving, frequency regulation, and black start features. Capable of bi-directional power flow, they transition smoothly between charge and discharge modes in milliseconds.
Perfect for balancing erratic solar wind power feeds. Our stackable converters maintain system voltage equilibrium on the DC bus. They manage the excess energy routing to localized battery storage or distribute power dynamically back into industrial networks.
Widely adopted by automotive testing facilities and recycling agencies. The dynamic current ranges (110A-160A) and flexible wide input/output windows (200V-1000V/1500V) support simulated EV driving profiles, capacity verification, and battery cycling applications.
