Design of the PWM Inverter Photovoltaics Tracking System for Maximum Efficiency

Since output of solar cell is direct current type, to apply ac load in the solar cell, inverter among power converters has to be necessarily installed in the solar cell. Power converter system was constructed with booster chopper and voltage source inverter and test was carried out for both devices. Constant voltage control method was used to track a maximum power point at boost converter control. In this paper, a boost chopper using photovoltaics system and PWM voltage type power converter were constructed to provide a pleasant environment to the patients in the hospital wards by controlling temperature, humidity and air-conditioning & heating.
