Abstract: The DC-DC converter with high step-up voltage gain is widely used for many applications such as uninterruptible power supply, solar-cell energy conversion systems, and high-intensity-discharge lamp ballasts for automobile headlamps. In these applications, a classical boost converter is normally used, but the voltage conversion ratio is not so high. Other techniques for boosting the voltage may lead to increasing the complexity of the circuit. This paper presents a high voltage boosting DC-DC converter topology intended for residential power systems. The high step up converter is based on charge pump capacitors and boost inductors. The converter will function appropriately even though boost inductor values are different.The output of this converter is connected to a single phase inverter for powering residential loads. The simulation is carried over by the MATLAB-Simulink.
