Abstract
A forward power converter with reduced harmonics for the input supply current is proposed. In this converter, the input capacitance is reduced, so that lower-order harmonics such as the fifth and the seventh can be largely reduced by about 20% to 40%. However, the DC link voltage ripple is increased in the proposed circuit. Such characteristics have been improved by a ripple compensation circuit consisting of the feedforward circuit. One can also obtain a noticeable harmonic elimination effect for the use of parallel connection between the proposed circuits and the conventional ones.<>
