Non-Isolated Point-Of-Load Converter for Space Application

With increasing demand for high power levels at optimized size, Point-of-Load (POL) converters are gaining popularity. Going by the name, POL converters are dc-dc converters dedicatedly designed for a particular load. These converters find their main use in space and defense applications that require very low and regulated voltages and higher currents, fast switching operations. This paper deals with the design and analysis of a POL system, for a space application fed from a 12V source, at 500 kHz. Closed loop implementation has been done using peak current mode control and the hardware results have been analyzed.
