The ACPL-P34X/W34X evaluation board allows a power inverter 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.

Features
● Half-Bridge topology
● Footprints for bootstrap power supply configuration
● Works for IGBT TO-220 / TO-247 type
● Able to evaluate the 4 A drive, rail-to-rail and speed performance
● Footprints for PCB mounting terminal blocks for wire connections to motor
● Split resistors network to achieve high CMR response
● Example of good bypass capacitors layout

Applications
● Isolated IGBT/MOSFET Gate Drive
● AC and Brushless DC Motor Drives
● Industrial Inverters
● Renewable Energy Inverters
● Uninterruptible Power Supplies (UPS)
