The figure shows one period of the output voltage of an inverter. α should be chosen such that 60° < α < 90°. If rms value of the fundamental component is 50V, then α in degree is __________.
-
- 61-65
- 76-77
- 36-47
- All of the above
Correct Option: B
| = | [1 - cosα - cosα + 0] | |
| π |
| = | [1 - 2 cosα] | |
| π |
| RMS Value of V01 = | [1 - 2 cosα] | |
| π √2 |
| ⇒ 50 = | [1 - 2 cosα] | |
| π √2 |
α = 77.15°
