Technician A say the inverter converts the voltage from 270 VDC to 14 VDC to recharge the auxiliary battery and to power 12-volt electrical components. Technician B says the convertor converts HV battery DC voltage into three-phase alternating current (AC) for MG1 and MG2. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Quizplus · Accepted Answer

The inverter converts DC voltage to AC for the motor-generators (MG1 and MG2), while a DC-DC converter reduces high voltage DC to 12V DC for the auxiliary battery and electrical components.
