Fig. 1 shows a single phase full-bridge converter. Fig. I single phase full-bridge converter 1.1 Analyse and determine the waveforms for the output voltage and the load current for an inductive load (10). 1.2 For the circuit in Fig. 1, supplies a load of
R=10\Omega ,L=31.5mH
, and
C=112\mu F
. The dc input voltage is
Vs=220V
and the inverter frequency is
f_(o)=60Hz
. The output voltage has two notches such that the third and fifth harmonics are eliminated. Evaluate the expression for the load current
i_(o)(t)
. If an output C filter is used to eliminate seventh and higher order harmonics, determine the filter capacitance
C_(e)
