LINE CONNECTION TYPE INVERTER USING REACTOR INTEGRATED TRANSFORMER

摘要

PURPOSE: A line connection type inverter is provided to be capable of preventing a distortion factor from being increased owing to a ripple of an output current. CONSTITUTION: A DC voltage link capacitor(Cd) receives a DC voltage and supplies an instantaneous current according to a switch operation. A switch part(100) converts the DC voltage into an AC rectangle wave voltage. A reactor-integrated transformer(102) filters and boosts the voltage of a rectangle wave, and makes it connect to a system power supply voltage. An AC capacitor(Cp) for a low pass filter is configured to reduce a ripple of the output voltage.
