a) b) c) d) converter (chopper) from a LiPo battery of 12 V. The chopper operates with switching frequency of 4 kHz. The load resistance and inductance are 10 and 50 mH, respectively, so that the converter operates in the continuous conduction mode. The switching components can be considered as ideal. Determine the required duty cycle and chopper on-time if the chopper output average voltage is 8 V. Calculate the average load current and the power delivered to the load for the case considered in part a). After certain time the battery has discharged, and the battery voltage dropped to 10.2 V. Calculate the new values of duty cycle and chopper on-time needed to maintain the same voltage on the output. How much power is now taken from the battery?
