In this paper, it is proposed to constant power control of solar power system<br/> The solar power system has disadvantage that low power density and variable power output Proposed strategy is controled by DC/DC converter using phase shift PWM and 1- PD type control applying type I digital system.<br/> The validity of proposed control strategy is verified from simulations results using PSIM.

In this paper, we firstly proposed to the boost type PFC circuit for a power factor improving and a harmonic decreasing. The predict current control method is used to control these PFC circuit This current control method has a merit that is possible to improve power factor and harmonics. In addition, we suggested to the active DC filter, which is connected with the DC output terminal, in order to compensate the DC ripple components. Consequently, these results are proved by the simulation tool, PSIM, which is an exclusive simulator of power electronics.
