Increasing Voltage Gain by New Structure of Inductive Switching DC-DC Converter

In a photovoltaic system, sun light energy is converted to electricity. The generatedelectricity has a low DC voltage. In order to increase voltage generated by photovoltaic cells (PV),an additive DCDC converter is required to raise the low voltage to a good level which provides theconditions for connection to DCDC converters. Low wastes, low costs, and high efficiency are someother specifications of such converters. This paper presents a new structure for an additive DCDCconverter with inductive and capacitor switching for increasing high voltage gain to be used in PVsystem. It is based on the inductive and noninsulated switching which increases voltage in a duty cycleup to 10 times of input voltage. In addition, using a switch, low elements, and also low voltage stresson the switch is the advantage of this new setup. The easy increasing of levels to reach the highervoltages is another benefit of this structure. The paper continues with the analysis of circuit functionand PWM (Pulse Width Modulation) adjustments. PSCAD/EMTDC software is used for confirming theauthenticity of the performance of the suggested model. The results are presented.
