IS220PDIOH1B Coupling Capacitor Module

IS220PDIOH1B first add Vge and to be stable (cut-off bias -15V, conduction bias +15V), and then you can add Vce. Do not when the G-pole overhang or not stable on the addition of Vce (a few hundred a thousand volts), because of the coupling capacitance of the Cgc poles between the IGBT can be mistakenly on, so that too high a dv / dt caused by electrical breakdown and damage. In order to avoid the occurrence of the above phenomenon generally use the delay circuit method, so that Vce delay Vge about 0.2 seconds, which greatly improves the use of security, reliability, especially in high-power devices should be noted.

IS220PDIOH1B 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.

IS220PDIOH1B 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 report, it is different from the separation of the way the module is limited only to the replacement of the damage can be.
