In type A chopper source voltage is 100 V, d.c. ON period = 100 s, OFF-period = 150 s and load RLE consists of R = 2Ω , L = 5 mH, E = 10 V.
For continuous conduction average output voltage and average output current for this chopper are respectively
-
- 40 V, 5 A
- 66.66 V 28.33 A
- 60V, 25 A
- 40V, 20 A
Correct Option: A
| Average output voltage, Vo = αVS = | Vs | |
| T |
where, T = Ton + Toff = 100 s + 150 s = 250 s
| ∴ Vo = | × 100 = 40 V | |
| 250 |
| and Io = | = | = 5 A | ||
| R | 2 |
