Boost Converter
D This boost converter boosts the nominal voltage of DC 244.8 V that is output by the HV battery to the
maximum voltage of DC 650 V. The converter consists of the boost IPM (Intelligent Power Module) with
a built-in IGBT (Insulated Gate Bipolar Transistor) which performs the switching control, and the reactor
which stores energy. By using these components, the converter boosts the voltage. For details, refer to
Inverter Assembly Control on page TH-49.
D When MG1 and MG2 acts as the generator, the inverter converts the alternating current into the
maximum voltage of DC 650 V, and then the boost converter reduces the voltage to the nominal voltage
of DC 244.8 V, thus the HV battery is charged.
