ABSTRACT:
A gate control circuit for current-type inverter apparatus having an inverter formed of self-extinction devices connected in a bridge form, comprises a logic circuit, pulse stretchers and gate amplifiers. When a frequency command signal is applied to the logic circuit, the logic circuit generates pulse signals for turning on or off the self-extinction devices, and the pulse signals are delayed for predetermined time in their trailing edges in response to the leading edges of the signals by the pulse stretchers so as to be extended, are amplified by the gate amplifiers, and then are supplied to the gates of the self-extinction devices.
