Maximum power tracker

摘要: A buck regulator or impedance converter is disclosed for operating a current limited power supply such as photovoltaic array at near its maximum point. The point achieved the compliance voltage which an almost constant voltage. Means are provided sensing input of and using this sensed to control logic circuit which, in turn, controls duty cycle switching transistor. output from transistor coupled LC filter there load. circuitry, responsive voltage, manner maintain approximately thus peak
