ZVS Regulators

Power That Delivers

Higher, Smaller, First


DC-DC Non-Isolated Regulated

Vicor's range of buck and buck-boost DC-DC converters use a Zero-Voltage Switching (ZVS) topology, enabling high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables fast dynamic response to line and load transients.


Temp Icon HIGHER temperatures

A regulator is only as good as the power it can deliver in the actual environment it will be used in, Vicor ZVS Regulators deliver more power at higher temperatures versus the competition.

Higher Temps Graph Small
Efficiencies Icon HIGHER efficiencies

The heart of any ZVS regulator is the zero voltage switching topology that enables lower losses from higher input voltages creating higher conversion efficiency than the competition.
