3.1 Switching
Figure 3-1 through Figure 3-12 show the switching behavior waveforms. Each waveform reflects the following parameters:
- Ch 1 (dark blue) is Vsw_priL: switching voltage of primary low-side half bridge
- Ch 2 (light blue) is Vsw_priH: switching voltage of primary high-side half bridge
- Ch 3 (purple) is Vsw_sr: switching voltage of secondary SR MOSFET
- Ch 4 (green) is Ip: Current of primary side
