PWM converter eRHC acts as an Active Front End when used together with an inverter, in which the input current is changed to a sinusoidal wave to significantly suppress the harmonic current.
Relative harmonic content［%］
Role of Harmonics Suppressing Filter
Its power-factor control realizes the same phase current as the power-supply phase-voltage. The equipment, thus, can be operated with the power-factor of almost “1”.
Reducing input current harmonics allows to use a more compact, lower capacity power transformer, circuit breaker, and other equipment compared with a standalone inverter, cutting down on costs.
Comparison of input current waveforms
Regenerated energy from highly frequent acceleration/deceleration and vertical applications is returned to power supply side.
Reusing regenerative energy for other equipment enables energy saving.
As the current waveform is also sinusoidal during regenerative operation, no troubles are caused to the power supply system.
Simultaneous connections to multiple inverters
Energy recovered can be monitored by yourself without installing additional components. (Available soon)
Components with limited life time has been designed to operate for 10 Power years, same as the inverters from Fuji Electric.
