Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/069654
Kind Code:
A1
Abstract:
A power conversion device 10 comprises: serially connected flying capacitor circuits 11, 12 that are connected in parallel with a direct-current power supply; serially connected flying capacitor circuits 13, 14 that are connected in parallel with the direct current power supply and the serially connected flying capacitor circuits 11, 12; switching elements S1, S2 that are serially connected between output terminals of the flying capacitor circuits 11, 12; switching elements S3, S4 that are serially connected between output terminals of the flying capacitor circuits 13, 14; a first output terminal OUT1 that is provided at a center point between the switching elements S1, S2; and a second output terminal OUT2 that is provided at a center point between the switching elements S3, S4. A connection point between the flying capacitor circuits 11, 12 and a connection point between the flying capacitor circuits 13, 14 are connected to a center point of a direct-current power supply voltage and alternating-current power is output from the first output terminal OUT1 and the second output terminal OUT2.
