4.10 A dc-dc converter is connected to a 100 V d.c. source to supply an inductive load having 40 mH in series with 5 2 resistance. FWD is placed across the load. Load current varies between two limits of 10 A and 12 A. (a) Find the time ratio (duty cycle) and the frequency of the chopper. (b) Find the equivalent Thevenin resistance across the source and determine the average source current.

Consider the following circuit used to provide power for an induative RL load. The input voltage is V-100V and the load has a 50 impedance value. The thyristor is working at a frequency fs = 2 kHz. The discharge current is to be limited to 40A and the required dv/dt is 40V/us. If the value of Ce is equal to 0.14uF, then the snubber losses are equal to: R. V.
