(a)Design a forward converter to produce an output voltage of 30V when the input dc voltage is unregulated and varies from 150V to 175V. The output power varies from 20W to 50W. The duty ratio of the switch is varied to compensate for the fluctuations in the input dc source to regulate the output voltage at 30V. Specify: the switching frequency and range of required duty ratio of the switch, ii. the turns ratios of the transformer, iii. the value of L, and iv. the capacitance required to limit the output ripple to less than 0.2%. Your design MUST work for all operating conditions.
