                                                             Figure class A  chopper  circuit  V0- I0 characteristic

Mode I 

When  the chopper switch  is on V0= Vs  and current  flows in the direction  in this mode  V0 and I0  will be  positive.

Mode II

When the chopper SW  is OFFF V0 = 0 (Since  diode  act like short Circuit). Now  the inductor present in the load releases its energy and  maintain the current in  the same direction through  the freewheeling diode FD.  Again the V0  and I0 will be  positive. This  operation is shown in by the hatched area in figur.
