WebApr 8, 2024 · The flyback converter also allows the possibility of using pulse width modulation (PWM) in a continuous mode of operation, as shown in Figure 2. It also allows the usage of feedback loops to maintain good control over the output voltage, even if the input current and voltage are changing. WebApr 9, 2024 · Both capacitors have ripple because inductor current rises or falls. You have the output ripple figured out, either the inductor current is large enough so current can charge the cap, or the inductor current is low so cap must discharge into the load. Same goes for the input capacitor.
