Abstract :
The paper proposes a sine wave current control method suitable for single phase grid connected inverter. The current signal is compared with a sine wave current reference, and the result is used to control the state of power switches. The control strategy calculate the on and off time of the switches attempts to let the output current equals the reference at the end of the chop period. The method eliminated the delay of sampled-date control method and is more stable and robust.
