Figure 1. Comparing SiC with conventional Silicon MOSFETs reveals the clearly superior semiconductor characteristics of the SiC material, which allows the construction of significantly smaller switching devices
The lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity – valuable in space saving applications. In addition, the electric-breakdown- field for SiC (approximately 2.8 MV/cm) allows for a much

Figure 1a and 1b. Due to the limited access for repair and maintenance of base station and cell towers, long life operation is required
Temperature control of sensitive telecom electronics in unattended mobile base stations and cell towers is vital for the operation of primary and back-up systems. Heat can significantly degrade the performance and operating life of telecom cabinets, energy storage systems and back-up battery systems. Mobile

Figure 1: DC-DC converters can be isolated or non-isolated
When Allesandro Volta made a battery out of copper and zinc disks and brine-soaked cardboard, it was a novelty and the low power DC produced had few practical applications. As electricity became better understood and it was discovered that rotating magnets could induce AC current in wires, the world of power

Figure 1: Average plant response to PAR
The horticultural lighting industry is in the middle of a disruptive change – growers are now getting to grips with the LED ‘solid-state’ artificial light alternative, traditionally provided by high-pressure sodium lamps (HPS). HPS lamps are relatively efficient at 100-150 lumens per watt, actually similar

Figure 1. Simplified block diagram of the ISL78714 multi-cell Li-ion battery manager
BMS designers have learned how to optimize BMS measurements and achieve high performance in an electrically and environmentally hostile automotive setting. The designers focus is still on cell measurement requiring millivolt and milliamp accuracy, and time-synchronizing these voltage and current measurements
