Abstract

The present disclosure relates to a conversion circuit, an inverter, and a method of driving the inverter, wherein a switch is provided at an input terminal of a direct current (DC) link capacitor, so that power is charged in the DC link capacitor through a switching element at initial driving and charged in the DC link capacitor through a rectifier when a voltage level of the DC link capacitor is equal to or higher than a preset reference level, thereby limiting inrush current caused in the DC link capacitor through the switching element when the inrush current is caused.
