Key points
- Vdc equals 2Vm over pi times cos alpha, so 200 times cos 60°.
- Cos 60° is one half, so Vdc is 100 volts.
Takeaway: At α = 60°, a full converter gives half its zero-delay output.
Quick check: A full converter with highly inductive load has 2Vm/π = 200 V. Find Vdc at α = 60°.
- 173 V
- 100 V
- 150 V
Cos 60° = 0.5: at α = 60° a full converter gives exactly half its maximum.
