BSM75GP60 Circuit Diagram

The circuit diagram shown is for the BSM75GP60, a 3-phase IGBT power module commonly used in industrial motor drives and power conversion applications. This module integrates several main power components within a single package to simplify high-power design.

On the left side of the diagram, pins 1, 2, and 3 represent the AC input lines (U, V, W), which are connected to a three-phase full-wave diode bridge rectifier. This section converts AC power into DC by directing current through six diodes arranged in a bridge configuration. The output of the rectifier is presented at pins 21 (positive DC) and 23 (negative DC), while pin 22 is the intermediate DC bus. The center part of the diagram illustrates three half-bridge IGBT inverter legs. Each leg contains an IGBT switch with an anti-parallel diode. These are connected as follows:

- IGBTs 13–14 and 20–19 form the upper and lower switches of phase U (output at pin 7).

- IGBTs 12–11 and 18–17 form phase V (output at pin 4).

- IGBTs 15–6 and 16–5 form phase W (output at pin 5).

Each pair allows controlled switching of the DC power to create three-phase AC output for motor control or inverter applications. Pins 8 and 9 are connected to an NTC thermistor, which provides temperature sensing for thermal protection and monitoring. This helps in maintaining safe operation of the module under varying load and thermal conditions.
