Description
1756-RM Embedded Integrated Power Devices
The 1756-RM is a comprehensive integrated power device designed for use in the main circuit of an inverter. 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:
1756-RM integrated all the 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 device is bad, it will result in the overall report of the loss, which is different from the separation of mode module, limited only to the replacement of the damage can be.
