All Semiconductor Switch Technologies Lead to Rome

Figure 1: Si superjunction and SiC MOSFETs have a vertical structure; GaN MOSFETs on the other hand have a lateral structure

Much is made of wide bandgap technologies, especially since GaN and SiC often have a superior performance on paper when compared to classic Si switching devices. These improvements include lower on-resistance and higher thermal conductivity, features that enable improvements in efficiency and operation at higher te

Figure 1. Simplistic inductor equivalent circuit

Despite its long history, the theory of magnetics component design still eludes many engineers, and with some justification; a good description of the effect of a magnetic field is the ‘relativistic correction to the force between charged particles when in motion.’ Many understand the behaviour of magnetics co

Figure 1: Waveforms during Startup Phase

Internet-connected devices rely on two core features, communications backhaul and power. With IoT devices, three core concerns regularly crop up: power, communications and security. Wireless technologies, like WiFi, have held the spotlight in the marketplace for years, but they struggle with these three problems. Wi
