Abstract
An insulated switch includes: a switch circuit connected between a first node and a second node and configured to be turned on and off by a switch drive signal; a pulse generation circuit configured to generate a first drive pulse and a second drive pulse in different phases; a switch drive circuit configured to receive a third drive pulse and a fourth drive pulse to generate the switch drive signal; and a first insulation capacitor and a second insulation capacitor configured to transmit the first drive pulse and the second drive pulse as the third drive pulse and the fourth drive pulse, respectively, while insulating the pulse generation circuit and the switch drive circuit from each other.
