Higher volumetric power density means lower robot weight for the same level of power delivery as alternative lower power density solutions, which extends operating time between battery recharges; this is a critical end-customer purchasing consideration. For autonomous vehicular robots, including limbed humanoid robots, an important power delivery criterion is “massimetric power density.” This is measured in continuous output watts per gram (W/g). Robot weight defines many performance aspects given the physical constraints of battery size, cost and aggregate, the multiplicity of technical, economic and performance-based advantages that 48V power delivery networks enable for next-generation equipment hardware designs are extremely compelling. Vicor power modules offer industryleading high voltage (800V/400V to 48V to 12V) zonal bridging, and low-voltage, high-current point-of-load solutions that address all modern hardware design requirements. With the world’s first ChiP™ (Converter housed in Package) high volume fabrication process, and a fully vertically integrated and automated factory, Vicor is ready and able to meet today’s advanced 48V power module demands. www.vicorpower.com Figure 5: EVs are migrating toward 48V power delivery networks with 12V zones to accommodate legacy subsystems. Vicor compact, lightweight DC-DC converters make point of load conversion easy and highly efficient. Figure 6: Humanoid robots have numerous power domains with diverse loads. Vicor’s broad family of 48-centric power modules adds flexibility to the design process and can accommodate many loads with high efficiency. chemical power density. Every opportunity to reduce weight is valuable, including the weight of the power delivery 48V DC-DC converters. 48V DC-DC converters appropriate for robot designs are capable of delivering more than 60W per gram (2kW at 29 grams) – a solid benchmark for regulated output converters. Power Modules Accelerate the Adoption of 48V These two real-world market segment examples illustrate and underscore the tremendous advantages that 48V-centric (HVDC to 48V and 48V to 12V) highpower-density modules bring to a broad spectrum of industrial, high-performance computing, aerospace and defense and automotive power system designs.
