Patent ID: 7236020

Claim:
A switched bridge circuit comprising: a first switch coupled to a load; a second switch coupled to said load; a non-overlapping pulse generator coupled to said first switch and said second switch and coupled to an input signal, wherein said non-overlapping pulse generator in response to said input signal generates a first control signal and a second control signal that respectively control said first and second switches, wherein pulses in said first and second control signals are not overlapped so that said first and second switches are not simultaneously enabled; a first edge detector coupled to said non-overlapping pulse generator for detecting rising and falling edges of said first control signal to generate a first plurality of pulse signals; a second edge detector coupled to said non-overlapping pulse generator for detecting rising and falling edges of said second control signal to generate a second plurality of pulse signals; a first D type flip-flop coupled to said first edge detector and said first switch for forming a first switch signal in response to said first plurality of pulse signals, said first switch signal controlling said first switch; and a second D type flip-flop coupled to said second edge detector and said second switch for forming a second switch signal in response to the second plurality of pulse signals, said second switch signal controlling said second switch.
