Understanding the next generation of industrial grid, storage, and clean generation technologies.
Traditional silicon insulated-gate bipolar transistors (IGBTs) are reaching their thermal and switching limits. Deming Power is integrating Silicon Carbide (SiC) and Gallium Nitride (GaN) wide bandgap semiconductors into our bidirectional DC-DC converters and high-speed microturbine generator converters. This change reduces switching losses, allowing efficiency rates to exceed 99% while minimizing system footprint.
Global ports are adopting cold ironing technologies to reduce localized sulfur oxide (SOx) and nitrogen oxide (NOx) emissions. Modern solid-state frequency converters must manage transient grid drops, variable reactive power requirements, and synchronization sequences without causing local grid disruptions. Our 6000kW systems utilize multi-level inverter topologies to ensure seamless grid transfers for large container ships.
Battery energy storage systems (BESS) require bi-directional power systems capable of sub-millisecond response times. Fast frequency response (FFR), synthetic inertia, and black-start capabilities are becoming standard requirements for global grid operators. By integrating active thermal management, galvanic isolation transformers, and advanced CAN/RS485 modbus configurations, our converters provide stable performance at these high operational limits.
Green hydrogen production via water electrolysis requires stable, ripple-free DC power at low voltages and high currents. Our triple-output isolated DC-DC converters act as interfaces for hydrogen fuel cell test platforms, permitting accurate testing and simulation of fuel cell stacks under varying load profiles.
Direct technical answers for engineers, utility developers, and procurement leads designing carbon-neutral power systems.
International vessels run on different voltage standards (e.g., 6.6kV or 11kV) and grid frequencies (50Hz in Europe/Asia vs. 60Hz in North America). Solid-state frequency converters rectify the incoming port utility AC voltage to DC, then invert it back to the required vessel AC frequency and voltage. This isolation protects the local grid from harmonic disturbances and voltage fluctuations generated by the ship's internal machinery.
A bidirectional Power Conversion System (PCS) operates in both charge and discharge modes. During off-peak hours, it acts as a rectifier, converting AC grid power to DC to charge battery banks. During peak demand or voltage sags, it functions as an inverter, feeding stored DC battery power back into the AC grid. Isolation transformers protect the sensitive battery cells from grid-side surges.
Hydrogen fuel cell stacks generate high DC currents at variable voltage levels. Without isolation, common-mode noise and leakage currents can damage the fuel cell catalysts or distort measurement sensors. Our triple-output isolated DC/DC converters provide physical isolation between the fuel cell under test and the main DC bus, ensuring stable data capture and safe operation.
Direct-drive PMGs run at varying speeds depending on wind velocity, generating variable frequency and voltage. An AC/AC converter rectifies this unstable AC input to DC, and then inverts it to a stable, grid-synchronized frequency and voltage. This system maintains optimal power extraction across a broad wind speed range without needing a high-maintenance mechanical gearbox.
Micro gas turbines operate at speeds up to 100,000 RPM, producing high-frequency AC power. Standard converters cannot process these high frequencies. Deming's specialized converters utilize fast-switching IGBT modules and DSP-based digital control algorithms to convert high-frequency input to standard grid frequencies with up to 99% conversion efficiency.
