Avago ACPL-P343 (W343) IGBT栅极驱动方案
The ACPL-P34X/W34X evaluation board allows a powerinverter designer to easily test the drive, rail-to-rail and speed capability of the ACPL-P343/W343 gate drive optocoupler.
The evaluation board includes two separate gate drive channels (one optocoupler per channel) making it a half-bridge topology for driving directly the gates of high-side and low-side IGBTs of a power inverter (such as single-phase motor inverter or one phase of a 3-phase motor inverter). This evaluation board can also support ACPL-P341/W341 and ACPL-P340/W340.
