Drive circuit for switch
In a drive circuit, a reference voltage generator generates a reference voltage that monotonically increases in a direction to pass through the threshold voltage during a voltage at the control terminal being lower than the Miller voltage. A buffer unit supplies the reference voltage output from the...

| description | In a drive circuit, a reference voltage generator generates a reference voltage that monotonically increases in a direction to pass through the threshold voltage during a voltage at the control terminal being lower than the Miller voltage. A buffer unit supplies the reference voltage output from the reference voltage generator to the control terminal of the switch, and adjusts a first transfer rate of electrical charge to or from the control terminal of the switch during at least part of a Miller period to be higher than a second transfer rate of electrical charge to or from the control terminal of the switch during the voltage at the control terminal of the switch passing through the threshold voltage. The Miller period is a period during which the voltage at the control terminal of the switch is maintained at the Miller voltage. |
