Title:
DUAL-POWER PHOTOVOLTAIC INVERTER AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/192813
Kind Code:
A1
Abstract:
A dual-power photovoltaic inverter formed by a preceding-stage conversion circuit and a subsequent-stage inverter circuit; the subsequent-stage inverter circuit is a three-phase inverter circuit; the preceding-stage conversion circuit supplies power for the subsequent-stage inverter circuit via a positive power supply wire (P) and a negative power supply wire (N); the preceding-stage conversion circuit consists of at least one dual-power conversion unit; and the dual-power conversion unit consists of a first capacitor (C1), a second capacitor (C2), clamping capacitors (C3, C4, C5, C6), a first converter (Cv1) and a second converter (Cv2). The dual-power conversion unit in the preceding-stage conversion circuit reduces costs and improves efficiency.
