A voltage regulator for an airconditioner using photovoltaic effect

摘要

PURPOSE: A voltage controller of an air conditioner using a photovoltaic effect is provided to economize energy by improving the voltage controller. CONSTITUTION: A solar cell(100) is used for receiving solar energy from sun and converting the solar energy to DC power. A power conversion portion(200) is used for converting the DC power applied from the solar cell(100) to AC power. A phase detection portion(600) is used for detecting a phase of the AC power. A comparison portion(800) is used for detecting a voltage of the AC power and comparing the detected voltage of the AC power with a reference voltage. A phase controller(500) is used for comparing a DC voltage of the solar cell(100) with a reference voltage in order to control a phase of the AC power. A PWM(Pulse Width Modulation) control circuit(400) is used for performing a PWM process for the AC power. A base drive circuit(300) is used for driving an AC conversion portion.
