A current sensing circuit that determines an output current of a bi-directional converter circuit comprises a current transformer that receives a first current signal and that outputs a second current signal. The first current signal is indicative of the output current and flows in one of a first direction and/or a second direction. The second current signal is indicative of the first current signal. A current sensing module receives the second current signal and has a first state and a second state. A converter control module simultaneously transitions the first current signal from the first direction to the second direction and transitions the current sensing module from the first state to the second state. The converter control module transitions the current sensing module to the first state after a resetting period.
