ABSTRACT

10kV linked SVG module power supply from their own h-bridge power, supply is unstable. To solve this problem, this paper proposes a new way to take power, using a combination of full-bridge push-pull circuit with isolation transformer to solve the logical drive power between the power module and the SVG device self-consistent problem. The paper detailed analysis of the working principle and characteristics of this new way to take power, and verified on prototype, present the experimental results.
