Abstract

In this paper, we propose a boost type inverter system for the compensation of instantaneous voltage sag. The system compensate instantaneous voltage sag which magnitude is higher than 10[%] of normal input voltage. When input voltage is higher than 90[%] of normal value, the switch in boost converter is not operated and output voltage is controlled by modulation amplitude in PWM inverter.
