Abstract
A first controller controls the DC-DC converter to perform a step-up operation when a voltage on the DC bus is lower than a first reference voltage and controls the DC-DC converter to suspend the step-up operation when the voltage is equal to or higher than the first reference voltage. A second controller controls the inverter to maintain the voltage on the DC bus constant when the voltage on the DC bus is lower than a second reference voltage and controls the inverter to maximize an output power of the inverter when the voltage is equal to or higher than the second reference voltage.
