Best Intermediate Bus Supply (IBC) Alternative Solution

The intermediate busbar architecture power system has become the mainstream of the current communication power system due to its advantages such as short design cycle, small impact between loads, and convenient maintenance. This structure is the most widely used distributed power system structure, which consists of front-end converters, intermediate busbar converters, and load point converters. The front-end converter converts the AC input into 48V DC, the intermediate busbar converter converts 48V into 12V and realizes electrical isolation, and the load point converter converts 12V into the voltage required by the load.


SynQor announced that it has won the patent lawsuit regarding open-loop and semi-regulated bus converters for intermediate bus architecture applications. Artesyn, Astec, Bel Fuse, Cherokee, Delta, Lineage Power, Murata, Power-One and 11 other companies will compensate SynQor for a total of more than 95 million US dollars. This lawsuit prohibits power suppliers other than SynQor from producing open-loop and semi-regulated bus converters. Generally, power users must have two or more suppliers for power products to ensure the security of the supply chain, so many equipment manufacturers are also quite troubled by this matter.

How to solve this problem?

As the largest power module supplier in China, China Electronics Huaxing actively seeks various alternatives to ensure the interests of customers. Here we introduce an alternative product to everyone - VI BRICK Intermediate Bus Converters.


VI BRICK Intermediate Bus Converters are bus conversion modules developed by Vicor based on V·I chips. They completely avoid the patented technologies of SynQor open-loop and semi-regulated bus converters. They are now available in 1/4 brick and 1/8 brick packages. It is worth mentioning that this series of products is fully compatible with the pins previously provided by other manufacturers and can be installed without changing the board.


According to the engineer of the marketing department of China Huaxing, there are 12 models of VI BRICK Intermediate Bus Converters series bus conversion modules launched this time. Taking IB050E120T32N1-00 as an example, this product supports wide input, input voltage range is 36V-60VDC, 4:1 voltage conversion, and output is not stable. The maximum power of 1/8 brick is 300W, the efficiency is as high as 97.8%, and the input and output isolation voltage is 2250VDC. The switching frequency is as high as 1MHz, ultra-low noise, meets various domestic and international safety standards, provides overvoltage/undervoltage protection, overtemperature protection and short-circuit protection, and can withstand a temperature range of -40℃ to +125℃. It is widely used in communications, military industry, data transmission, and server equipment systems.


China Electronics Huaxing believes that this series of products is a key product to solve the supply of busbar power modules for communication equipment manufacturers. For more product information, please consult the marketing department of China Electronics Huaxing.
