Abstract

A gate drive adapter circuit includes an input circuit, an output circuit, and a charge pump circuit. The input circuit is configured to receive pulses suitable for controlling a silicon power transistor. The output circuit is coupled to the input circuit. The output circuit is configured to translate the pulses to voltages suitable for controlling a silicon-carbide power transistor. The charge pump circuit is coupled to the input circuit and to the output circuit. The charge pump circuit is configured to generate a negative voltage. The output circuit is configured to apply the negative voltage to translate the pulses.
