A schematic design of a full-wave bridge type power supply is given below. Provide the appropriate values for the inductors, diodes, capacitor and resistors, such that the output DC voltage is 6.2 V and the max. output power for the load resistance is 20 mW (percentage error for output voltage and output power is 2%). AC voltage source: Amplitude=311.13, Freq=60, DC offset= 0. For the rectifier part, choose diodes with an appropriate PIV rating. Show all the formulas and computations involved in acquiring the values for the inductors, diodes, capacitor and resistors. In choosing your Zener diode, consider the output voltage and the output current. Note that the output current should be the minimum Zener current. For the value of the series resistor RS, choose a lower value for less ripple but always consider the required output voltage. The ripple voltage peak-to-peak value should be less than or equal to 1% of the required output voltage. Use the formula below for choosing the value…
