1-Phase Full  Bridge  inverter will RL Load

For a  resistive load R the load  current  wave form  will be  identical with load  voltage wave form  and feedback  diodes will not  come into  conduction. In  the case of RL -Load  the wave form  of output current is  shown in the  circuit of 1-? full bridge  inverter with Rl load  is shown .

Before t =0  thyristors T3 and T4 are conducting and load  current is flowing in  negative direction. After  T3 and T4  are turned of at t=0  load current  io can not change its direction immediately due to the existence of inductance in the load. Therefore  after t= 0 diodes D1 and D2 start conducting and  allow the  load  current  to flow  against  the source voltage. Load voltage becomes  Vdc.

At t=0  thyristor  T1 and T2  are gated but these  thyristors will not  turn on because these are reverse biased by voltage drops across  D1 and D2. After the  load  current  becomes equal to zero T1 and  T2  start concocting up to  the period t = T/2  now  load  current  start flowing in positive direction ( as we  assumed in circuit) at  t= T/2 T1 and   T2 are  commutated and T3  and T4  are gated but tagging  the current can not change its direction immediately. As  a result diodes D3 and D4 starts conducting to allow the current to flow in positive direction. Thyristors T3 and T4 will not  start conduction until the  load current through diodes D3 and D4 falls  to zero because these thyristors will not turn  on as these  are reverse  biased by the voltage drops in the D3 and
