POWER SUPPLY ADAPTIVE FEEDFORWARD CONTROL CIRCUIT

摘要

There is provided by this invention a system for supply power utilizing a power supply having an adaptive feedforward circuit that uses a gating circuit to periodically apply a feedback signal to an integrator circuit in order to develop an optimal level of a scaled feedforward signal that is used to diminish perturbations of the output of the power supply due to ripple and transient voltages present at the DC bus that supplies power to the power supply. The gating circuit is synchronized to the periodic ripple in the DC bus voltage.
