Title:
A THREE-PHASE SINGLE SWITCH POWER FACTOR CORRECTING BOOST CONVERTER
Document Type and Number:
WIPO Patent Application WO/2002/052708
Kind Code:
A1
Abstract:
The present invention dicloses a three-phase single switch power factor correcting boost converter. It includes three-phase input, output, three-phase rectification circuit, pulse width modulation circuit, voltage loop and current loop. The positive input of the current loop is connected to the output of the voltage loop, the negative input is connected to the output of the current sampling circuit, and the output of the current loop is connected to the positive input of the pulse width modulation circuit. As long as the provided circuit parameters satisfy certain conditions, the input power range of the harmonic wave in IEL1000-3-2A standard may be increased greatly.
