New motor control software boosts BridgeSwitch ICs
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. 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

Figure 1: There are many choices when it comes to selecting the right plug for your external power adapter (Source: CUI)

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.  Engineers responsib

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

Space, but not as we know it - the new space race
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
