基于脉宽调制器的变频控制半桥和全桥变换器传递函数测量方法

Variable frequency control is widely used in half-bridge and full-bridge converters. Measuring the switching-frequency-to-output-voltage transfer function is critical to verify a derived model and guide the design of closed-loop parameters. The existing voltage-controlled-oscillator-based measurement method is complicated in circuit implementation and the accuracy could be affected by the bandwidt...
