DR1350-F4-1-45

The DR1350-F4 driver is a single–channel driver of high-power high-voltage IGBT transistors designed for galvanically isolated control of one powerful transistor with a maximum permissible voltage of up to 4500 V. The driver is an amplifier – generator of transistor gate control signals with a frequency of up to 20 kHz.

The driver is designed for operation in combination with the MIP-DR-65 power supply, which provides the necessary levels of logic, unlocking and locking voltages.

The driver provides the following control, monitoring and protection functions for the controlled transistor:

1. transistor control with the status of the front and rear control edges;
2. control of the saturation voltage on the collector of a controlled transistor;
3. smooth shutdown when exiting the saturation state in half-bridge mode;
4. no shutdown when exiting the saturation state in three-level mode;
5. blocking the control in case of an accident in half-bridge mode;
6. alarm about the presence of an accident;
7. monitoring of supply voltages with undervoltage protection;
8. active protection of the controlled transistor against overvoltage during switching of an inductive load and in case of an accident (Active clamping);
9. bypass of the shutter at shutdown (Miller clamping).
