AC Link Chopper
This copper has two stage conversion. First DC is converted into AC by the use of inverter. The magnitude of AC voltage is varied by the transformer and it is converted back to dc using a rectifier.

Q. A single-phase industrial plant consists of two loads in parallel: P1 = 48kW PF1 = 0.60 lagging P2 = 24kW PF2 = 0.96 leading It is operated from a 500-V, 60-Hz source.
What current must flow if 0.45 coulombs is to be transferred in 5 ms? Quantity of electricity, Q = It, then:
p type material: p type material is formed by doping aerial crystal with impurity atoms having three valance electrons. The diffused impurities with three valence electrons
Explain the Power Chart The phasor diagram shown in Figure with the x and y axes added, as shown. This diagram may be converted to a 'power chart' by multiplying each phasor in
