Igbt Gate Drive Transformer

The dielectric strength voltage is 2 6 kv.

Igbt gate drive transformer.

A gate drive transformer isolates the controlling gate drive circuit from the switch node when driving the mosfet gate and may also scale the output voltage via an appropriate primary to secondary turns ratio. Isolation transformers with high withstand voltages are required in the igbt gate drive power supplies of motor inverters for xevs. Designed for transformer coupled mosfet and igbt gate drive circuits. For more information see the overview for mosfet and igbt gate drivers product page.

The required number of windings is usually given by the circuit topology while the. It consists of four alternating layers p n p n that are controlled by a metal oxide semiconductor mos gate structure without regenerative clarification needed action. Texas instruments application report slua618 march 2017 revised slup169. Procedure for ground referenced and high side gate drive circuits ac coupled and transformer isolated solutions are described in great details.

Fundamentals of mosfet and igbt gate driver circuits. Tin silver over tin over nickel over phos bronze terminations. Industry standard ep5 surface mount package. They also are used for voltage isolation and impedance matching.

Operating frequency from 50 khz to 2 mhz. Cots plus tin lead terminations available. A special section deals with the gate drive requirements of the mosfets in synchronous rectifier applications. The products in this series successfully combine a shift to high coupling low leakage with a shift to completely automatic winding by employing a new structure that makes automatic winding possible resulting in isolation transformers that can provide stable output.

High flux density cores have been adopted to achieve miniaturization. These devices provide electrical pulses for turning on and off semiconductors such as high voltage power mosfets or igbts. A gate drive transformer is optimized for transmitting rectangular electrical pulses with fast rise and fall times to activate or deactivate a switching device. A gate drive transformer is needed in a smps to control the timing of the circuit.

Gate drive transformers are essentially pulse transformers that are used. Need parts for space military or other critical.
