Abstract:
1. A current sense rectifier circuit comprising: an assembly input terminal to receive a current input signal, the current input signal having an alternating current (AC) waveform; a negative half-wave circuit to generate a first input signal representative of negative portions of the current input signal, the negative half-wave circuit including a single diode in connection with a resistance, wherein the single diode of the negative half-wave circuit includes an anode and a cathode; a positive half-wave circuit to generate a second input signal representative of positive portions of the current input signal, the positive half-wave circuit including a single diode in connection with a resistance; a closed-loop amplifier having an inverting input terminal, a non-inverting input terminal, and an output terminal, wherein the inverting input terminal is connected to the negative half-wave circuit to receive the first input signal, and the non-inverting input terminal is connected to the positive half-wave circuit to receive the second input signal, wherein the closed-loop amplifier inverts the first input signal, wherein the output terminal generates a direct current (DC) voltage output signal as a function of the inverted first input signal and the second input signal; and an assembly output terminal connected to the output terminal of the closed-loop amplifier to receive the DC voltage output signal therefrom; wherein the anode is connected to the inverting input terminal of the closed-loop amplifier, and the cathode is connected to the assembly input terminal, and wherein the resistance of the negative half-wave circuit is connected between the anode of the single diode of the negative half-wave circuit and a ground potential.
