A power converting system for a vehicle may include: a high-capacity on board charger (OBC) configured to charge a high-capacity high-voltage battery. a low voltage DC-DC converter (LDC) configured to convert a high voltage of the high-capacity high-voltage battery into a low voltage and charge a low voltage battery. The power converting system may further include an OBC and LDC integrated controller configured to perform integrated control of the high-capacity OBC and the LDC. The OBC and LDC integrated controller performs pulse width modulation (PWM) switching control by synchronizing ADC operation and PWM switching frequency control operation.

Power converting system for vehicle and control method thereof

An apparatus for enabling a two-stage inverter to switch between modes includes: a first inverter unit, a second inverter unit, a load connected between the first inverter unit and the second inverter unit, a mode switching unit connected between the load and the second inverter unit, and a control unit configured to drive the load in an one-stage inverter mode or a two-stage inverter mode by performing a control that turns on or off the mode switching unit.
