Title:
ENERGY DOUBLE-FED DEVICE WITH PFC AND GRID COMPENSATION FUNCTIONS
Document Type and Number:
WIPO Patent Application WO/2016/054856
Kind Code:
A1
Abstract:
An energy double-fed device with PFC and grid compensation functions. The device is in an H-bridge structure. According to the control idea of a three-phase SVG and the idea of independent Id and Iq control, cost, circuit complexity, ease of development and adaptability are fully considered. An AC-DC converter and a DC-DC converter are used in the device, and the whole circuit allows bidirectional energy flowing through only six switch tubes. The AC-DC converter is used for energy transduction with a power grid. The basic idea of an H-bridge lies in a BOOST circuit, so that output voltage VH of the H-bridge is definitely greater than 311 V during 220 V single-phase power utilization, and the bidirectional DC-DC converter is added to meet the multiple demands of a user, DC-DC conversion is under current control, outputting of constant voltage 0-VH and constant current can be achieved, and constant current is fed back to the power grid.
