Once  a  diode  has  been  connected,  a  load  that  does  not  consume  power  keeps  its  voltage 

charged.  The  voltage  of  the  load  may  be  slightly  higher  due  to  the  overshoot  voltage  and 

should be carefully monitored.

b)  Inductive load such as inductor 

An inductive load generates a back EMF when current suddenly stops flowing, such as when 

the output is turned off. A backflow diode is required to absorb the back EMF. 

Connect a backflow diode in parallel with the load, as shown in 

Figure 4-2
