In order to provide power supply for transmission line monitoring equipment, a photovoltaic and super-ca-pacitor based switching power converter is suggested. An improved charging circuit with switching capacitor and Boost converter is put forward, and the maximum power point tracking( MPPT) control system based on ARM7-LPC2138 is proposed. The new power supply can not only track the maximum power point, but also charge the super capacitor rapidly. The prototype for the proposed power supply has been developed. Simulation and experiment results verify the feasibility of the proposed approach.
