V CONCLUSION A novel single-phase isolated converter had designed with careful nature for interconnection grid purpose applications. We observed that ripple current in a dc power supply, such as a fuel cell, battery, or photovoltaic cell, can be reduced by the appropriate operation of a dc active filter. VI REFERENCES [1] S.
