Title:
INVERTER POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/192666
Kind Code:
A1
Abstract:
An inverter power system (10), comprising an inverter circuit (100) and a feedback circuit (200); the inverter circuit (100) is used to convert a first alternating voltage into a second alternating voltage, and convert a first alternating current into a second alternating current; the feedback circuit (200) determines whether the magnitude of the second alternating voltage exceeds a preset threshold, and if yes, then the feedback circuit (200) obtains a feedback current, and compensates for the reference value of the first alternating current according to the feedback current, generates a control signal according to the compensated reference value of the first alternating current, and outputs the control signal to the inverter circuit (100) to adjust the magnitude of the second alternating voltage.
