Question

Your group has been asked to design a portion of a power supply which reduces the variation due to ripple from the rectifier stage. The completed power supply is intended to provide 300W of 48V DC power to an RF transmitter. The transformer stage transforms a 3-phase AC power source at 60 Hz from 120 V RMS to 50V RMS, which is rectified before being applied to your circuit. You are designing the regulator, not the rectifier. The input to your circuit is guaranteed not to fall below 60V DC, but may vary as high has 65V DC. You can perform this design with Zener diodes and ordinary diodes, design the circuit.
