I'm excited to share my latest project with you - the design of a 50V 95A 4750W synchronous Boost converter.
Built around the 765kHz LTC3787 controller, it features 10 phases each generating 50V 9.5A with a voltage ripple of 0.32% (324mV per phase) to optimize overall performance. The theoretical efficiency reaches 95.4% at full load.
The main challenge in this project was twofold: first, to effectively select components given the current global situation, and second, to manage tracks efficiently that were meant to carry 50A each while minimizing the number of layers in the PCB stack-up and thermal dissipation through joule effects without relying on buried vias or microvias. We also had to effectively manage the total thermal dissipation of 234W while still abiding by the dimensional constraints specified in the requirements. Solidworks simulations were necessary to optimize thermal performance.

The board was designed using Altium Designer software.

He stopped communicating in the middle of the project, rarely responding to any messages, eventhough we have seen him online. During the project, He came up with different excuses on not being responsive, we gave him more time about a month but midway he completely stopped communicating and didn't respond anymore. For us the most important factor in a relationship/business, is trust and reliability, which we didn't find here and hope he works on improving it.
