STRUCTURE AND OPERATION
On-board Charger
OPERATION PRINCIPLE
1.AC power which is externally given is rectified to DC power with rectifier circuit 1.
2.The voltage of the rectified DC power is boosted during the power factor improvement in the PFC circuit.
3.The voltage-boosted DC power is converted back to AC power with the inverter.
4.The AC power from the converter is boosted by the insulated transformer and is rectified to high-voltage
DC power by rectifier circuit 2.
5.The rectified high-voltage DC power is output by the output circuit.
NOTE:
PFC (Power Factor Correction) circuit is a power factor improvement circuit. It is a device for converting AC
power (input from external source) to DC power efficiently.
