Vicor Corporation

Vicor Corporation is an American manufacturer of modular power conversion components headquartered in Andover, Massachusetts. The company was founded in 1981 by physicist Patrizio Vinciarelli (Princeton), who still serves as Chairman, President and CEO and remains the principal inventor behind Vicor's architectures and topologies.

Vicor specializes in high-density isolated and non-isolated DC-DC converters in modular packages (ChiP, SM-ChiP, VIA). Key product lines include DCM (regulated converters), BCM (fixed-ratio bus converters), PRM (pre-regulators) and VTM (voltage transformation modules that work with PRM as part of the proprietary Factorized Power Architecture). The Sine Amplitude Converter topology enables very high switching frequencies and efficiencies up to 98%, resulting in minimal losses and aggressive miniaturization.

Vicor's largest end markets are AI/HPC (powering NVIDIA H100/H200/B200 GPUs from a 48 V bus down to 12 V and core voltage via BCM and low-voltage regulators), automotive (48 V mild-hybrid, EV, ADAS), defense and space (MIL-COTS, VPX, LEO satellites), unmanned aerial vehicles, and robotics — particularly humanoids, where extreme power density in a tightly constrained envelope is critical. Vicor is listed on NASDAQ under the ticker VICR (S&P 400 MidCap component). The company operates its own manufacturing facilities and holds a portfolio of over 200 patents; it has a global footprint through 11 subsidiaries in the U.S., Germany, France, Italy, the U.K., Japan, Hong Kong and mainland China.
