Low Profile, High Density AC Front End
Vicor’s new VI BRICK® AC Front End moduledelivers an isolated, PFC regulated, 330W 48V output in a low profile module only 9.55mm in height. This AC–DC converter which operates over the universal AC input range of 85-264 V, provides high efficiency and a power conversion density of 121 W/in3 (7.5W/cm3) or 54 W/in3 for a complete supply that includes all necessary components including hold-up capacitance.
This integrated solution streamlines your design and can help reduce your time to market. The AC Front End’s comprehensive feature set includes:
- Small Package and Profile
- 3.75” x 1.91” X 0.38” (95,3 X 48,6 X 9,55 mm)
- Integrated rectification, filtering and transient protection
- enables you to configure a complete front end system that meets IEC 61000-3-2 harmonic noise and Class B EMI conducted emission limits
- Agency approvals and certifications in place
- facilitates faster design and product delivery
- Active PFC (Power Factor Correction)
- meets EN 61000-3-2 and saves energy by matching voltage and current sinusoidal waveforms to minimize energy loss in high voltage transmission and reducing demand on power generators
- Output: 48 Vdc isolated, regulated
- Power: 330 W over the entire input voltage range
- Peak efficiency: greater than 92%
- across its entire AC input voltage range, including operation down to 85VAC
- reduces power loss and cooling requirements by 50%
The AC Front End’s significant efficiency performance is powered by Vicor’s proprietary DC-ZVS (Zero-Voltage Switching) Adaptive Cell™ topology. The topology allows for high efficiency across high line and low line conditions.
The AC Front End will be available through distribution at the end of the year.
