WebFlyback Converter with Voltage-Mode Control Keng Wu, in Power Converters with Digital Filter Feedback Control, 2016 3.2 Modulator gain With the power stage designed and waveforms formulated, it can now be incorporated with the feedback loop, input filter, PWM block, and switch driver. The flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage. There are three common ways to generate this voltage: 1.
