More cost-effective power converter module option

16 November 2005 Power Electronics / Power Management

Vicor is offering a new, lower cost option for its high performance line of second generation DC-DC converter modules and Vipac Arrays: the E-Grade versions.

The manufacturer says that these DC-DC converter modules use advanced power processing, control, and packaging technologies to provide high power density, flexibility and reliability, along with cost effectiveness achieved through high volume manufacturing. High frequency ZCS/ZVS switching provides high power density with low noise and high efficiency.

Targeted applications include off-line systems with autoranging or PFC front-ends, industrial and process control, distributed power, medical, ATE, communications, defense, and aerospace.

E-grade modules and power systems are priced approximately 15% below the company's C-grade versions. They are available in four different input ranges (24, 48, 300 and 375 V), seven different output voltages (2-48 V), and three package sizes (quarter, half, and full brick). Different baseplate and pin options are also available. Efficiency ranges from 80-90% depending on output voltage, operating temperature range is -10 to 100°C and storage temperature range is

-20 to 125°C.
