Abstract
A switch current sensor includes a summing circuit, at least one first-type switch current sensor subcircuit and configured to be coupled at a first input to a conductor, and coupled at a first output to the summing circuit, and at least one second-type switch current sensor subcircuit configured to be coupled at a second input to the conductor and coupled at a second output to the summing circuit. The summing circuit is configured to aggregate the first output of the at least one first-type switch current sensor subcircuit and the second output of the at least one second-type switch current sensor subcircuit to obtain a voltage waveform that is proportional to a switch current configured to flow in the conductor, the voltage waveform including a DC component and steady-state AC components of the switch current.
