WebThe ﬂyback converter uses a two-loop control scheme. The inner current loop, based on a peak current mode controller, provides a fast transient response, and the outer voltage … WebMost flyback converters use secondary-side peak current-mode control of the secondary-side converters to adjust feedback for the output voltages as in Figure 1. The secondary-side output voltage is fed back through the TL431 and the optocoupler to the primary-side. grass cutter ps4
