1,2 kW DC-DC power modules

4 June 2014 Power Electronics / Power Management

Vicor unveiled the first module utilising its converter housed in a package (ChiP) power component platform. The new bus converter modules (BCM) supply

1,2 kW at 48 V with 98% peak efficiency and 115 W/cm³ power density. These performance levels are ideal for high-voltage DC distribution infrastructure in data centre, telecom and industrial applications.

With a nominal input voltage of 380 V (full range of 260 to 410 V) and a K-factor of 1/8, the fixed-ratio power converters support outputs ranging from 32,5 V to 51,25 V. They are based on Vicor’s ZCS/ZVS Sine Amplitude Converter topology and operate at a 1,25 MHz switching frequency, providing fast response time and low-noise operation.

Offered in the 6123 ChiP package, the new 380 V d.c. VI Chip BCMs measure 63 mm by 23 mm, with a height of only 7,3 mm. Initially offered as a through-hole device, package options will also include SMD variants. ChiP BCMs may be paralleled to provide multi-kW arrays and are capable of bidirectional operation to support battery backup and renewable energy applications.

Standard BCM features include under-over-voltage lockout, over-current, short circuit and over-temperature protection. ChiP BCMs incorporate digital telemetry and control features that can be configured to meet customer requirements.
