3) Voltage Drop Conversion Function
The alternating current, which is generated by MG1 or MG2 for the purpose of charging the HV battery,
is converted into maximum voltage of DC 650 V by the inverter. Then, a function of the boost converter
drops the voltage to nominal voltage of DC 244.8 V. This is accomplished by the IGBT (1) switching
ON and OFF through duty cycle control, which intermittently interrupts the electrical power provided
by the inverter.
