IC693CPU374-GP is a comprehensive integrated power device designed for use in the main circuit of inverters. For example, the 2.5-66A 1200V series and 4-75A 600V series produced by TYCO in Munich, Germany, it contains single-phase/three-phase input rectifier bridge + braking unit (or PFC power factor unit) + six units of IGBT + NTC temperature monitoring. However, the drive circuit is not included. Some professional factories, such as Fuji, rectifier, braking, IGBT, protection, drive, control all integrated module, so that the use of more convenient, safe and reliable. Its characteristics are:

IC693CPU374-GP integrated all the devices and circuits; B, small size, high power, low loss, more stable; C, optimise the internal wiring, reduce parasitic noise; D has a complete self-protection circuit with fast, sensitive; E, the only shortcoming is that when one of the devices is bad, will cause the overall loss, which is different from the separation of way module, limited only to the replacement of the damage can be.

IC693CPU374-GP inverter internal measurement circuits, protection circuits, drive circuits, conversion circuits, isolation circuits, CPU, gate circuits, etc., the electronic devices used, such as TTL, COMS, op-amps, optocouplers, etc. are provided by the switching power supply to provide the required different voltage values, for the IGBT in terms of the Vge by the switching power supply to provide ± 5-15V voltage, but Vce is provided by the main Circuit filtered by the three-phase rectifier bridge DC power supply (P N) provided to ensure that the use of IGBT safety and mis-conductivity, so the order of Vge and Vce plus voltage requirements.
