The Switch Mode Power Supply (SMPS) has been achieved the high power density and high performance by developing the power semi-conductor devices such as IGBT, BJT, MOSFET, GTO, etc. SMPS has the capacity to handle the variable loads and variable input voltage. The efficiency, weight and size of power supplies are a great area of concern for the power supply designers. This paper introduces the method of intelligent regulation to control the buck converter using the pulse width modulation switching by a fuzzy logic controller.
