a) Design a dc chopper circuit to produce an output of 60 V from a 25 V source. The circuit is operated in continuous inductor current and an output ripple voltage of less than 0.007%. Given the switching frequency is 40 kHz and the load resistance of 30 W. Assume the inductor value is 25% larger than Lmin and ideal components for this design. Identify the chopper type and construct the circuit with MOSFET as the power switching device.
