Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC B  H  Y | IPC B  H

Claim 0:
1. An on-board charger comprising:
a first stage for converting an alternating current (AC) voltage from an external power supply to a direct current (DC) voltage;
a capacitor coupled to the first stage to receive the DC voltage and to provide a DC-Link voltage;
a second stage coupled to the capacitor to boost the DC-Link voltage and to supply the boosted DC-Link voltage to charge a battery; and
a processor programmed to:
set the DC-Link voltage to a constant voltage value in response to the AC voltage from the external power supply exceeding a threshold value, wherein the threshold value is equal to 140 Volts AC; and
adjust the DC-Link voltage between a first setpoint and a second setpoint based on a battery voltage value, in response to the AC voltage being less than the threshold value.
