05704-A-0121 Embedded Integrated Power Devices

05704-A-0121 Comprehensive integrated power devices designed for use in the main circuit of inverters. For example, 2.5-66A 1200V series and 4-75A 600V series produced by TYCO in Munich, Germany, it includes 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:

05704-A-0121 integration of all devices and circuits; B, small size, high power, low loss, more stable; C, optimise 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, it will result in the overall loss of the report, which is different from the separation of way module, limited only to the replacement of the damage can be.

05704-A-0121 inverter internal measurement circuits, protection circuits, drive circuits, conversion circuits, isolation circuits, CPU, gate circuits, etc., the electronics used, such as TTL, COMS, op-amps, opto-couplers, etc., are supplied by the switching power supply to provide the required value of different voltages, the IGBT to speak of the Vge by the switching power supply to provide ± 5-15 V voltage, but the Vce is the main circuit by the DC power supply (P N) provided by the three-phase rectifier bridge filter, in order to ensure the safety of the use of IGBT and false conduction, so the order of Vge and Vce plus voltage requirements.
