双移相加变频控制的隔离型双向AC/DC变换器控制策略
A Dual-phase-shift Plus Variable Frequency Control Strategy of Isolated Bidirectional AC/DC Converter
摘要
Abstract
A dual-phase-shift plus variable frequency control strategy of isolated bidirectional AC/DC converter is proposed. By applying variable frequency control, the original nonlinear relationship between shifting-phase ratio and output power in dual-phase-shift control is converted to a linear relationship. The strategy is easy to apply and able to reduce switching loss. Moreover, the intermediate capacitance is small, decreasing the size of the converter. By analyzing the operation principle of the proposed strategy, the requirement of switches to zero-voltage switching-on in dual active bridge is presented. Simulation and experimental results verify validity of the proposed strategy.关键词
