3.1 Switching
Figure 3-1 through Figure 3-7 show the switching behavior. Each waveform reflects the following parameters:
- Ch 1 (dark blue) is load current
- Ch 2 (light blue) is switching voltage of one primary side half bridge
- Ch 3 (purple) is output voltage
- Ch 4 (green) is resonant current in primary side
