INTEGRATED LOW VOLTAGE DC-DC CONVERTER WITH ACTIVE BATTERY BALANCING BETWEEN MODULES AND BATTERY BALANCING METHOD USING THEREOF

According to an embodiment of the present disclosure, a power conversion device included in a power system may include a conversion circuit configured to transform a direct current (DC) voltage output from batteries, and a balancing circuit connected to a primary side of the conversion circuit and configured to balance states of charge of the batteries, the balancing circuit may perform driving so that a balancing target battery among the batteries is charged or discharged based on a gate signal for the conversion circuit, and the balancing target battery may be connected to the balancing circuit based on an average voltage of the batteries.
