Title
Discordant splitting capacitance drives system bus voltage pulsation suppression
Abstract
This paper analyzes the power decoupling performance of the mismatched split-capacitor half-bridge circuit, and reveals the mechanism of fundamental harmonic generation in the circuit through the mathematical model of the decoupling circuit established. In order to solve this problem, firstly, this paper proposes a control strategy of introducing DC bias coefficient on the basis of instantaneous voltage control of split capacitor C-1. Secondly, using instantaneous voltage of capacitor C-1 as control quantity can better realize voltage tracking control effect, with fast response speed and simple control. Finally, the effectiveness of this control strategy is verified by experiments.
