Abstract :
The stability properties of the forward and the flyback inverter are compared. A free-running inverter is not suited for grid-connected applications. The realisation of a high open-circuit gain in a system with an externally determined switching frequency and without the loss of the power capacity is discussed. A 250 W low-distortion grid-connected forward inverter has been realised.
