| In a photovoltaic system, sun light energy is converted to electricity. The generated electricity has a low DC voltage. In order to increase voltage generated by photovoltaic cells (PV), an additive DC-DC converter is required to raise the low voltage to a good level which provides the conditions for connection to DC-DC converters. Low wastes, low costs, and high efficiency are some other specifications of such converters. This paper presents a new structure for an additive DC-DC converter with inductive and capacitor switching for increasing high voltage gain to be used in PV system. It is based on the inductive and non-insulated switching which increases voltage in a duty cycle up to 10 times of input voltage. In addition, using a switch, low elements, and also low voltage stress on the switch is the advantage of this new setup. The easy increasing of levels to reach the higher voltages is another benefit of this structure. The paper continues with the analysis of circuit function and PWM (Pulse Width Modulation) adjustments. PSCAD/EMTDC software is used for confirming the authenticity of the performance of the suggested model. The results are presented. | ||
