Abstract:
A drive circuit of a power semiconductor element comprises a gate drive voltage generator to generate, based on an ON/OFF drive timing signal input to an input terminal, a gate drive voltage to be applied to a gate electrode of a switching element having the gate electrode for controlling a main current that flows between a first main electrode and a second main electrode, wherein the gate drive voltage generator includes a gate current limiting circuit in which a current limiter to limit a current and a voltage limiter to limit the magnitude of a voltage applied to both ends of the current limiter are connected in parallel.
