3.1 Switching Waveforms
Switching behavior is shown in the following figures. Test conditions for these waveforms occur at:
- VIN: 230 V
- VOUT: 400 V
- IOUT: 10 A
Note: Several operating points are illustrated to demonstrate the topology and controls ability to maintain ZVS when the input voltage is both above and below ½ VOUT.
- CH1 - VSW Phase 1
- CH2 - VSW Phase 2
- CH2 - ISW Phase 1
- CH4 - ISW Phase 2
