ABSTRACT:
A ripple reducing circuit wherein ripple voltages across the output terminals of a voltage source are coupled through a ripple sensing circuit to an amplifier. The sensed ripple is amplified and phase reversed to provide signals in phase opposition to the ripple signals. These phase opposition signals are coupled via an anti-ripple element to the output terminals of the voltage source for effecting ripple level reduction.
