The single phase half-wave controlled rectifier with inductive-load. The waveshapes for voltage and current in case of an inductive load.
The load is assumed to be highly inductive.
The operation of the circuit on inductive loads changes slightly. Now at instant t01t01 , when the thyristor is triggered, the load-current will increase in a finite-time through the inductive load. The supply voltage from this instant appears across the load. Due to inductive load, the increase in current is gradual. Energy is stored in inductor during time t01t01to t1.t1. At t1,t1, the supply voltage reverses, but the thyristor is kept conducting. This is due to the fact that current through the inductance cannot be reduced to zero.

During negative-voltage half-cycle, current continues to flow till the energy stored in the inductance is dissipated in the load-resistor and a part of the energy is fed-back to the source. Hence, due to energy stored in inductor, current , current continuous to flow upto instant t11t11 at instant, t11,t11,the load-current is zero and due to negative supply voltage, thyristor turns-off.

At instant t02,t02, when again pulse is applied, the above cycle repeats. Hence the effect of the inductive load is increased in the conduction period of the SCR.

The half-wave circuit is not normally used since it produces a large output voltage ripple and is incapable of providing continuous load-current.
