Abstract :
This paper proposes a control algorithm for utility interactive PWM inverters to maintain a continuous, uninterrupted voltage across critical and sensitive loads in the event of a fault on the grid. The algorithm switches the inverter between voltage-controlled and current-controlled modes and can easily be implemented using a DSP
