Generate at variable speed
A diesel engine drives a high-frequency permanent-magnet generator and produces variable-frequency three-phase power.
Vehicle-mounted permanent-magnet generator conversion for dependable emergency power.
WD610A converts variable-frequency generator output into stable three-phase four-wire 400 V, 50/60 Hz power, with grid-connected, parallel and island operation engineered for the project.

Decouple engine speed from the quality of the delivered power.
Emergency power vehicles must deliver stable electricity to communications, rescue, utility support and other critical loads while working within strict vehicle space and payload limits. A conventional low-speed generator set can make output frequency directly dependent on engine speed.
WD610A controls current, torque and DC-link energy on the generator side, then regulates voltage, frequency and phase on the load or grid side. This allows a high-frequency permanent-magnet generator to operate over a more flexible speed range while users receive standard utility-frequency power.
Control generator energy
WD610A regulates generator-side voltage, current and flux, supporting stable conversion across the operating range.
Decouple through the DC link
The DC link separates engine and generator speed from the output frequency required by user loads or the grid.
Deliver standard AC power
The load/grid side produces three-phase four-wire 400 V, 50/60 Hz power with project-specific mode and protection logic.
One four-quadrant platform for compact mobile generation.
Power conversion, mode control, cooling, protection and vehicle integration are engineered as one system.
Variable-frequency input
Standard generator-side input covers three-phase 350–450 VAC and 50–550 Hz. Other frequencies require target engineering.
Stable utility-frequency output
The output side forms three-phase four-wire 400 V power at 50 or 60 Hz for vehicle distribution and external loads.
Grid and island operation
Virtual synchronous generator, pre-synchronization and droop strategies support grid-connected, parallel and off-grid/island modes.
Compact modular construction
The platform covers 50–300 kW. 85–200 kW uses an integrated structure; the 300 kW version uses an upper/lower split arrangement.
SiC and liquid cooling
Silicon-carbide power devices and water cooling support high power density and reduce the thermal burden inside the vehicle enclosure.
Open system interfaces
RS485, CAN, analog and digital I/O, voltage sampling, encoder and operator interfaces support commissioning and vehicle controls.
Built around the complete vehicle powertrain.
The final solution coordinates the engine, high-frequency generator, WD610A, liquid-cooling loop, distribution equipment and vehicle control system.

Designed for vibration, thermal load and emergency-duty environments.
WD610A uses a 125°C-class DSP, high-junction-temperature SiC devices, film DC-link capacitors, conformal coating, vibration isolation and liquid cooling. Source documentation also lists EMC immunity tests and a 72-hour uninterrupted full-load test.
Grid-connected projects additionally require switchgear, synchronization detection, anti-islanding and protection aligned with local grid requirements.
Vehicle-mounted generator converter questions.
Is WD610A an electric-vehicle traction inverter?
No. It is a permanent-magnet synchronous generator converter for diesel-driven mobile, shipboard and stationary generation systems.
Why does a mobile generator need a converter?
A high-speed generator's voltage and frequency change with speed. The converter decouples that variable input from the stable 400 V, 50/60 Hz output required by loads.
Can it support both grid and island operation?
Yes, with project-specific VSG, pre-synchronization, droop, switchgear, anti-islanding and electrical protection design.
How is the 300 kW version installed?
It uses an upper/lower split, narrow structure with separable control and heavy power components, mistake-proof connectors and a series cooling path.
