Design of universal power supply with two isolated auxiliary input using common transformer and common secondary outputs
I want to design SMPS with below specifications:
Input: IN1: 60VAC-280VAC, IN2: 60VAC-280VAC
Output: Out1: 5V/0.5A, Out2: 12V/0.5A, VA: 10
Isolation required between two input supply is of 5KV for HV test.
Single transformer to be used for both inputs at different winding and only one switcher work at a time based on priority.
Please suggest best compatible design solution.
