Page 9: Operational Principle
2.2Operational principle The input AC sine wave is transferred to DC bus voltage of 400VDC by rectifier with PFC technology. The process is as following: the main AC input is filtered by the LC and rectified by SCR (HT33010XL/XS is rectified by relays and diodes), then the source is boosted to 400VDC by the booster consisting of rectifier IGBT, inductance and capacitors. -
