A circuit for converting an alternating voltage into a rectified voltage includes a first transistor having a first terminal, a second terminal, and a control terminal. The first terminal is configured to receive the alternating voltage via an input terminal, and the second terminal is electrically coupled to an output terminal for outputting the rectified voltage. A control circuit includes a first input, a second input, and a first output. The first input is electrically coupled to the first terminal of the first transistor, the second input is electrically coupled to the second terminal of the first transistor, and the first output is coupled to the control terminal of the first transistor. The control circuit is configured to generate a first control signal based on a first voltage at the first input and based on a second voltage at the second input. The conversion circuit also includes a resistive circuit.
