A new transformer less Photo voltaic inverter with bidirectional capability has been developed where the concept of High Frequency Leg (HFL) is used. This allows the use of high switching frequency which reduces the size of the filter elements. As the number of legs is increased, the power handling capacity of the inverter is increased and the inductor current ripple is reduced. The bi directional feature of this inverter has made it more attractive for PV applications.
