  • Patent number: 11277125
    Abstract: A drive circuit drives driven switches connected in parallel with one another. The driven switches each include first, second main, and main control terminals. When a potential difference of the main control terminal with respect to the second main terminal becomes greater than or equal to a threshold voltage, the flow of current between the first and second main terminals is permitted. At least two driven switches have different threshold voltages. The drive circuit includes, for each driven switch, an electrical path electrically connecting the second main terminal or a negative voltage supply, which is at a negative voltage lower than the potential of the second main terminal, to the main control terminal. The impedance of each of the electrical paths is set so the potential difference increased by electric charge flowing into the electrical path through a parasitic capacitance of the driven switch becomes less than the threshold voltage.
