Configuring for Power Density and Connectivity

Figure 1a

­The availability of modular, configurable power supplies provides industrial and medical system designers with an approach to develop systems that address application-specific requirements without time and resource consuming custom design or compromising with less optimal standard, off-the-shelf solutions. As the funct

Figure 1: Cooling/heating effect at the conductors’ junctions during current flow (Peltier effect)

­Some remote sensors are required to stay active in the field for a period longer than it’s possible for a suitably sized battery to last. In such cases, an energy harvesting system may be added to extend the operating lifetime. Available ambient energy sources can include kinetic energy present in vibrations, li

Figure 1: Sumida covers all inductors for switched-mode power supplies and partially and fully implements application-specific components

­The high-frequency (HF) transformer and other inductors form the core of a switched-mode power supply (SMPS). Located in the input section, the interference suppression components ensure suppression of interference voltages and currents on the power supply lines. Current-compensated chokes (common-mode chokes) s

Figure 1: Simplified power architecture of satellite with SA50-120 series converter

­Space satellites use solar energy as the main source to power its loads. A simplified power architecture is shown below as shown in Figure 1. with Radiation Hardened (Rad-Hard) standard SA50-120 series DC-DC 50 W power converters from Microchip. Some of the commonly used bus voltages are 28V, 50V, 72V, 100V
