Power devices including high-power semiconductors, indium gallium bipolar transistors, and metal oxide semiconductor field effect transistors are controlled and switched by gate drive transformers, also known as GMTs. These devices are essential in modern power electronics. Transformers primarily drive and isolate these devices' gates, ensuring their reliable, efficient, and safe operation in high-voltage environments.

What is a gate drive transformer?

Gate drive transformers supply voltage and current to power semiconductor gates like IGBTs and MOSFETs. The GDT ensures switching performance by separating the gate circuit from the power circuit and supplying the voltage to turn the semiconductor on or off.
Gate drive transformers are crucial in motor drives, power supplies, inverters, and renewable energy systems for switching frequency and efficiency. These transformers can safely and reliably handle high-speed switching and high-voltage circuits.

Functions Crucial to Gate Drive Transformers

1.       Isolation: GDTs are crucial for galvanic isolation between low-voltage control and high-voltage power circuits. This separation protects control electronics from power side voltage spikes and surges.

2.       Voltage Conversion: Gate drive transformers raise the control circuit's low-voltage logic level to operate a power device's gate. This is crucial in high-power situations where the gate drive voltage must exceed the control logic level.

3.       High-Speed Switching: The ability of GDTs to manage high-frequency switching is crucial in situations where power devices need to turn on and off quickly. Examples of fields where this is prevalent include controllers for industrial motors, renewable energy systems, and electric cars.
