A solar energy installation utilize a three – phase bridge converter to feed energy into power system through a transformer of $$400V/400 V,$$ as shown below. The energy is collected in a bank of $$400$$ $$V$$ battery and is connected to converter through a large filter choke of resistance $$10\Omega $$.

The $$kVA$$ rating of the input transformer is

A voltage commutated chopper circuit, operated at $$500Hz,$$ is shown below. If the maximum value of load current is $$10A,$$ then the maximum current through the main $$(M)$$ and auxiliary $$(A)$$ thyristors will be

A three-phase current source inverter used for the speed control of an induction motor is to be realized using MOSFET switches as shown below. Switches $${S_1}$$ to $${S_6}$$ are identical switches.

The proper configuration for realizing switches $${S_1}$$ to $${S_6}$$ is
