High-Voltage Isolated Half-Bridge Driver (Up to 1kV)

This fully isolated half-bridge driver is designed for high-voltage applications up to 1kV. It features 2 x 2W isolated DC-DC converters to independently power the low-side and high-side switching elements. The board is assembled with 1.2KV IGBTs, Two power LEDs provide visual indication of power presence for both the low-side and high-side gate drivers. The signal ground is galvanically isolated from the power ground, allowing it to be connected to any potential up to 2.5kV. Barrier connectors are provided for the load and its power supply. A screw terminal connector facilitates the 12V DC input for the gate driver circuitry. A LM78M05 regulator provides a 5V supply to the logic side of the gate driver input circuit. A header connector allows for PWM input via channels A and B, as well as enable/disable control.
