A passive R-L load is supplied from a step-down DC-DC converter (chopper) from a LiPo battery of 15 V. The chopper operates with switching frequency of 4 kHz. The load resistance and inductance are 9 and 60 mH, respectively, so that the converter operates in the continuous conduction mode. The switching components can be considered as ideal. a) Determine the required duty cycle and chopper on-time if the chopper output average voltage is 11 V. da ton = les b) Calculate the average load current and the power delivered to the load for the case considered in part a). A P= w c) After certain time the battery has discharged, and the battery voltage dropped to 13.8 V. Calculate the new values of duty cycle and chopper on-time needed to maintain the same voltage on the output. d2 = ton2 = his d) How much power is now taken from the battery? P= w
