Electric motors are responsible for using a huge portion of the electricity we generate. Some estimates put that figure almost half of global energy consumption. As such, it makes sense to have the motors driven as efficiently as possible, for the user to save costs, for the supplier who won’t face so large deman

Figure 1. Conventional AC power source topology
Programmable AC power sources have been widely used to implement and support numerous product test procedures over the years. They provide the test engineer with the ability to fully control voltage, frequency, and current to the unit under test (UUT). Products like these are used to simulate various power conditions an

This is partly due to packaging requirements and partly due to the bespoke requirements for individual use cases. This drives up the cost of components for high-power applications as there is very little economy of scale. Infineon has tried to buck this trend somewhat with its new EasyPACK CoolSiC MOSFET module that

Designing for space applications used to be really difficult and very expensive. At the beginning of our exploration of space, spacecraft and satellites cost a huge amount of money, which at that time meant that only the largest companies and government organisations could afford to put manned vehicles and satellit

Figure 1: Si, SiC and GaN material characteristics
A basic building block in power conversion electronics is the semiconductor switch. The ideal is one with no static or dynamic losses that can withstand high voltage in the off state and with no leakage when on – but that is always just out of reach. One of the closest though is the wide band-gap technology Si

New product features tend to have a direct impact on the total power needed, which may mean increasing the capacity of dc-dc converters or increasing the number of regulators distributed throughout the design. Ultimately, feature-creep will also put greater demand on the main source of power.

Figure 1. On the left is the TSPD functional model and, on the right, a TVS diode
With low-power, high-speed data systems, standard TVS diodes are commonly used in combination with low capacitance diodes to reduce the parasitic capacitance in applications like HDMI 2.0, USB 3.1, and Gigabit Ethernet. TVS diodes have offered the smallest form factors possible without sacrificing performance. Bu
