WebAug 21, 2024 · Flyback converter is most widely used switched mode power supply (SMPS) topology. Flyback converter because of its simplicity, less number of components and providing the isolation between the source and load it is used in offline converters, computers, printers. Webcommon practice is to determine the worst case RHPZ frequency and set the loop unity gain frequency below one-thirdof the RHPZ frequency. In the Flyback topology, the equation for the RHPZ is: (5) The worst case RHPZ frequency is at the maximum load where IOUT is the highest and at minimum input voltage where the duty cycle D is the highest.
WebRHZ在boost, buck-boost, flyback(占空比由输入输出电压和匝比决 定)CCM中都存在,而DCM中没有RHZ。 负载突然增加→输出电压下降→EA+PWM 反应→占空比增大(Wrong Way)→反激时间减小→输出电流减小(通过输出diode)→输出电压下降更多 (临时)。 此即典型RHZ响应特性。 在DCM中，占空比增大导致输出电流增大，故不存在此RHZ O-B … WebFigure 1 --Flyback Circuit, Continuous Inductor Current Mode Figure 1 shows the basic flyback circuit operating in the continuous mode with its current waveforms.
