LYA210A Embedded Integrated Power Devices

LYA210A is an integrated 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:

LYA210A 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 the way the module is limited only to the replacement of the damage can be.

LYA210A inverter internal measurement circuit, protection circuit, drive circuit, conversion circuit, isolation circuit, CPU, gate circuit, etc., the electronic devices used, such as TTL, COMS, op-amps, optocouplers, etc. are provided by the switching power supply to provide the required value of the different voltages, for IGBT to say that the Vge is provided by the switching power supply ± 5-15V voltage, but the Vce is filtered from the main circuit by the three-phase rectifier bridge. Vce is provided by the main circuit filtered by the three-phase rectifier bridge DC power supply (P N), in order to ensure the safety of the use of IGBTs and false conduction, so the order of Vge and Vce plus voltage requirements.
