Voltage controlled switching element gate drive circuit
摘要:
A voltage controlled switching element gate drive circuit makes it possible to suppress an occurrence of a malfunction, while suppressing surge voltage, surge current, and switching noise, when switching in a voltage controlled switching element. A gate drive circuit that supplies a gate voltage to the gate of a voltage controlled switching element, thus driving the voltage controlled switching element, includes a high potential side switching element and low potential side switching element connected in series, first variable resistors interposed between at least the high potential side switching element and a high potential power supply or the low potential side switching element and a low potential power supply, and a control circuit that adjusts the resistance values of the first variable resistors.
