Novel insulated gate bipolar translator (IGBT) drive and protection circuit

The invention discloses an insulated gate bipolar translator (IGBT) drive and protection circuit. The circuit mainly comprises a power supply for providing working voltage, a voltage reference unit, an insulated-gate bipolar transistor (IGBT), a control pulse input circuit, an optical coupler P1, a primary amplifying circuit, a Vce monitoring and protecting circuit and a fault soft switch-off circuit and is characterized by also comprising an under-voltage protection unit for blocking the output of the drive and protection circuit when a power supply voltage falls to a set value and a rise and fall adjustable circuit for adjusting the switch-on rise time Tr and switch-off fall time Tf of the IGBT. The circuit has the advantages of perfect function, reliable performance and easy popularization and application.
