What is a Isolated gate driver?

An isolated gate driver is a circuit used in power electronics to drive switching devices such as transistors or IGBTs (Insulated Gate Bipolar Transistors). It provides electrical isolation between the input side and the output side. This isolation is essential for protecting the system from power supply and signal interference, thus enhancing the safety and reliability of the circuit.

Isolated gate drivers are commonly used in applications that deal with high voltages or currents, such as power converters, inverters, and motor control systems. These drivers can be found in solar power systems, electric vehicles, industrial machinery, and other similar applications. The driver physically separates the input and output signals, allowing them to be transmitted through an isolated path, thus avoiding direct connections between the control circuit and the power circuit. This reduces the risks of faults, overvoltage, and noise interference.
