Abstract:
A method may include controlling switches of a switching full-bridge of a signal processing system to commutate polarity of a capacitor with respect to the first processing path output and a second processing path output of the signal processing system in response to a condition for commutating connectivity of the switching full-bridge and inserting a feedforward compensation that bypasses a loop filter of the second processing path in order to prevent discontinuities caused by commutating polarity of the capacitor from being compensated by the loop filter.
