UPS Systems
Single and three-phase online UPS with low-THD output and high overload capability.
- Active front end (low input harmonics)
- N+1 parallel redundant inverters
- Thyristor and IGBT-based options
Power electronics design and manufacturing
Power conversion that runs where it matters: rails, industry and critical load.
We design and build UPS systems, railway converters, battery chargers, EV chargers and high-end DC-DC converters, with in-house hardware, magnetics and DSP firmware.

Selected work
Projects we've delivered
A sample of recent engineering. Customer details are withheld under NDA; technical discussions are available on request.
01
Three-phase UPS with active front end and N+1 paralleling
Three-phase online UPS with a PWM active front end for near-unity power factor and low input harmonics, feeding inverter modules that operate in parallel redundant (N+1) configuration with load sharing over CAN.
02
Railway regenerative battery chargers (RBC)
Battery chargers with regenerative discharge for railway battery conditioning, with precise CC/CV control and energy return to the grid instead of burning it in a resistive load.
03
Auxiliary converter for railway
Rugged auxiliary power converter for railway use, engineered for wide input variation, isolation requirements and the environmental stresses of rail service.
04
High-current thyristor 12 / 24 pulse systems
Phase-controlled thyristor rectifier systems in 12 and 24 pulse configurations for high-current DC loads, delivering reduced input harmonics, with digital firing control and protection.
