Document Type and Number:
WIPO Patent Application WO/2018/120828
Kind Code:
A1
Abstract:
A power supply converter, comprising a branch a, a branch b, a second transformer (T1B), a first transistor (Q1), a second transistor (Q2) and a first transformer (T1A). The power supply converter can not only accelerate the starting of a transistor, but can also improve the conversion efficiency, enhance a capacitive load starting capability, enhance a low temperature starting capability and realize a short-circuit protection function, and can work normally at different environmental temperatures. The power supply converter has a low no-load power consumption and has a long-term short-circuit protection function.
