ELECTRIC POWER CONVERSION DEVICE AND PROGRAM

WIPO Patent Application WO/2024/053460

A1

This electric power conversion device is equipped with: a higher arm switch (SWH) and a lower arm switch (SWL) which are connected in series; a first capacitor (21) which is electrically connected in parallel to the higher arm switch and the lower arm switch; a coil (11), a first end of which is electrically connected to the connecting point between the higher arm switch and the lower arm switch; a second capacitor (90); a higher potential-side electric path (22H) which is electrically connected to the higher arm switch; and a lower potential-side electric path (22L) which is electrically connected to the lower arm switch. A second end side of the coil is electrically connected via the second capacitor to one path among the higher potential-side electric path and the lower potential-side electric path. The second end side of the coil is electrically connected via a power storage unit (33) to the other path among the higher potential-side electric path and the lower potential-side electric path. The electric power conversion device is also equipped with a control unit (100) for switching between the higher arm switch and the lower arm switch.
