Abstract
This paper presents a high output voltage dc-dc converter that combines two circuit configurations, i.e. a two-phase interleaved boost at the input side and a charge pump circuit configuration operating based on voltage multipliers at the output side. When loads change, the converter output voltage changes also. Therefore, the converter output voltage is needed to be controlled. The input voltage is specified in 12V or 24V, which is fed from a battery. The controller unit generates two PWM signals to drive the converter output voltage constant at the 220V setpoint. The performance of the controller is tested by simulation under variable load conditions and under justified DC voltage variation at the input terminal. The simulation results show that the PI adaptive performance showing small overshoot compared with the PI static. This performance result will be useful to develop a home scale photovoltaic system in the future.
