Vicor-PDN-Betterfrost-xlarge

Figure 2 The Vicor BCM functions as a DC-DC transformer. A fixed-ratio converter reacts to power changes at a rate of 80 A/s. Betterfrost uses pulsed energy to melt a very thin interfacial ice layer in less than a minute (its record is 42 seconds) compared to 25 minutes for traditional HVAC systems. This technology uses a proprietary algorithm to melt the ice in uniform manner and while consuming 20x less energy than the legacy approach.
