Question
Three-phase half wave rectifier supply resistive load with DC power of 4 kW; the ammeter connected with D1 indicates 8 A r.m.s current, and the source frequency is 50 Hz Due to system inductance the average voltage drops to 96.2% of idealized value ( when the inductance is neglected).
- How much will the average and r.m.s voltage s be?
- The r.m.s phase current and average load current Is=? & Idc=?
- The secondary r.m.s voltage and transformer capacity Vs & KVA?
- The inductances causes the voltage drop Lc=?
- The diode forward current and maximum inverse voltage?
- Now, if the phase B is failed ( disconnected), how much with new dc voltage be in %..Vdc=….% ??
