New BCM in ChiP Packaging Technology for HVDC: More Power, Higher Input Voltage

We have just announced a new BCM designed for HVDC applications. The new device follows the announcement of the first BCM to use the ChiP platform a couple of months ago, and offers improved performance and increased functionality. The new device is optimized for up to 400 V DC nominal input voltage (260 to 410 V), supporting systems that use a 400 V HVDC bus, as well as those based on 380 V. It also offers significantly higher throughput, delivering 50V at 1.75 kW with 98% peak efficiency.
