The maximum power point tracking( MPPT) is the automatic control algorithm to adjust the power interfaces and achieve the greatest possible power. This paper describes the hardware circuit of maximum power point tracking control system and the program of improved P&O method. Hardware structure of this system is composed of MCU controller( STC15F2K60 S microcontroller),the voltage sampling circuit,the current sampling circuit,solar panels and the boost circuit. This method is simple,efficient and low cost of hardware,used in the small power of photovoltaic power generation systems.
