Design of 50W Electronic Power Conditioner using planar power magnetics

This paper describes the design and development of a 50W Electronics Power Conditioner (EPC) using planar power magnetics on a multilayer printed circuit board. The EPC outputs are selected as per the power requirement of Ku-Band SSPA Transmit Module for space applications. The main power converter is designed with forward topology using active clamp reset technique. Magnetic feedback technology with voltage mode control has been adopted for regulation. Multi-stage input filter is implemented to meet MIL-STD-461E standard. Another low power converter is also designed with forward topology using resonant reset technique, used to provide housekeeping supply as well as low power supply to the SSPA.
