INVERTER DEVICE AND METHOD FOR DESIGNING DUTY CYCLE SETTING SECTION OF INVERTER DEVICE |
摘要 |
An inverter device has a DC/AC inverter section that converts input DC voltage into AC voltage with a rectangular wave and outputs the AC voltage. A duty cycle setting section sets a duty cycle for controlling turning on and off of a switching element of the DC-AC inverter section by a controller. The duty cycle setting section determines the duty cycle using a signal based on the value of the DC voltage and a charging curve determined by a CR circuit. Accordingly, regardless of changes in the input voltage, the effective value of the output voltage approximates to a theoretical value compared to the conventional art.
