Showing various waveforms in the 12V 50A 600W switching power supply module on an analog and a digital oscilloscope. It's a 2 switch forward. The waveform on the main ferrite transformer, gate driving transformer (GDT), output inductor (on an iron powder core), MOSFET gates, primary smoothing capacitor ripple, output ripple, mains input current, changes in duty cycle, transistor current and so on.
