Abstract
There is provided a power conversion apparatus including first to fifth nodes. The power conversion apparatus includes: an inverter including a first switch between the first and second nodes, a second switch between the first and third nodes, a third switch between the second and fourth nodes, and a fourth switch between the third and fourth nodes; a filter including an inductor connected between the second and fifth nodes and a capacitor connected between the fifth and third nodes; and a current sensor configured to sense resultant current, which is the sum of inductor current flowing in the inductor and output current, wherein the output current is output to a load connected between the third and fifth nodes.
