Vicor Launches First Product in Revolutionary ChiP Package

Vicor Launches First Product in Revolutionary ChiP Package

Today Vicor announced the first product to use the revolutionary Converter housed in Package (ChiP) power component platform. The new ChiP bus converter modules (BCM®) deliver 48 Vdc with an output power of 1.2 kW, 98% peak efficiency and 1880 W/in3 (115 W/cm3) power density: a stunning four times the density of competing solutions. Gary Gill, Director, VI Chip product line at Vicor, was on-hand to answer our questions about the launch: This product uses new packaging: why is that important? This is the first product to be housed in the ChiP platform, which...

My Journey: Rapid Prototyping of a Cell-Based, High Performance, High Power DC-DC Converter (part 1)

My Journey: Rapid Prototyping of a Cell-Based, High Performance, High Power DC-DC Converter (part 1)

Have you ever wondered what an applications engineering job entails? This post is about a recent project I undertook; a journey through prototyping a cell-based demo kit for a high performance DC-DC converter, taking me from desk to demo lab in five working days. One Monday morning, I settled down at my desk to read a trip report a colleague had sent me. There were two pages of facts gleaned during a four-hour meeting with a client, addressing technical requirements for a well-funded, long-term project. Whilst I could have simply suggested some components that...

Live Webinar in Russian Explains How to Reduce EMI and Minimize Filter Size

Live Webinar in Russian Explains How to Reduce EMI and Minimize Filter Size

Reducing EMI is a key task for power system designers. With the pressure to increase density of modern electronic systems, engineers have limited PCB real estate for power supplies and EMI filters, putting pressure on engineers to achieve maximum filtering efficiency in minimal space. Lev Slutskiy, Technical Sales Engineer at Vicor, will present the second in a series of Russian-language webinars explaining how to meet the challenge of EMI on Wednesday, January 29, 2014 at 12:00 (Moscow). There is no charge to attend the webinar, but participants must register in advance. The webinar covers...

Back to Basics: How do I Ensure Correct Power Rail Sequencing in a Multi-Rail Power Architecture?

Back to Basics: How do I Ensure Correct Power Rail Sequencing in a Multi-Rail Power Architecture?

For a graphic illustration of why power sequencing is essential, consider what could happen in a large industrial system if its motors and actuators became energized before its control electronics. Clearly, the potential for such unpredictable and dangerous scenarios must be eliminated with carefully-designed power start-up sequences. And shutdown sequences are equally as important. Incorrect power sequencing can cause problems at the semiconductor as well as at the system level: these conditions could lead to unexpected reverse bias across a CMOS device. This can damage or destroy the device, or latch it into an...
