Dear members,
I'd like to design professional type DC-DC power supply requirements as
follows:
Input: 18...36 Vdc
Output: 18....24 Vdc @ 170W
Design shall be realized without Boost partion i.e.
under 24 V input, the output follows the input (23in = 23out, 18in = 18out etc.)...and over the 24 V input ,the output will be reagulated to be 24 V.
This could be realized with e.g. Buck regulator with PMOS top-fet i.e. could get almost 100% duty cycle....or by Formard Converter topology.
Problem with PMOS top-fet is high losses i.e. difficult to find such kind PMOS with small thermal loss.
Please help me if somebody has some experience this sort of problem?! Thanks!
