The quest for energy efficiency has focused attention on those components of the power electronics that can connect hundreds of volts and amps in inverters with exceptional efficiency. We are talking about modern power switches – IGBTs and SIC-FETs – and how the voltage supplied to the respective gate drivers
High-voltage IGBT-modules usually consist of two types of IC, an IGBT for the transistor and a diode for the freewheeling functionality. A device that combines both functions in a single die is known as a reverse conducting IGBT (RC-IGBT). These modules exhibit a lower thermal resistance when compared to an
Equipment designs increasingly utilize advanced MCU, DSP and FPGA devices to deliver the functionality and performance demanded of them. With this sophistication comes the challenge of providing the multiple power rails these devices require. The use of carefully chosen power modules can significantly ease this
Here we’ll look at how a rugged and flexible control can be rapidly implemented using an 8-bit microcontroller with analog blocks. For many custom power supplies, this provides an optimum combination of noise immunity, high performance, short development time, and digital flexibility.
People don’t think about engineers much, and in general engineers are looked upon in a positive light. Unless something goes wrong with something. In the marketplace, engineering is usually the first direction people point fingers when problems occur in a product.

Induction cooking appliances commonly make use of resonant topologies which allow bi-directional current flow. Additionally they demand a discrete IGBT that performs best at switching frequencies from 18 to 40 kHz and has low losses. Infineon Technologies launched a new family of discrete IGBTs to address these
A key consideration for wireless sensor nodes that will populate the Industrial Internet of Things (IIoT) is battery lifetime. The sensor nodes, in many applications, will need to be installed in locations that are difficult to reach and, consequently, service. Because it is too costly and difficult to run power
Oftentimes, designers of digital cameras, mobile devices and other consumer electronics choose to power their device from two, series-stacked, Lithium-Ion (Li-Ion) batteries, yet still desire the capability to charge from a 5-V universal serial bus (USB) port. Boosting a 5-V USB input to charge two series-stacked
In this PSDcast Karl Fleischmann of TI talks to Alix Paultre of Power Systems Design about USB Type-C development. Texas Instruments recently introduced a multiport USB Type-C and Power Delivery (PD) minidock reference design that provides audio, USB data, power and video support. This new TI Designs reference
Having a good grasp of how measurement tools actually operate can provide valuable insight into how test methods can be improved. Setups can subsequently be made simpler and more effective, plus test performance parameters can be significantly raised. This is true for any sphere of technology that requires the

LGA package technology can deliver important advantages for the high-performance Point-Of-Load converters needed to feed power-hungry, fast-reacting data centers and network infrastructure. As the power demands of high-performance Cloud and telecom computing systems continue to increase, converter modules that
Continuing the old story-telling tone which began the issue, I would like to point your attention to the centuries-old proverb “For want of a nail” which describes a chain of events and their consequences from a small error snowballing into catastrophe. There are many lessons to draw from this, from the
Here we’ll explore the analytical transfer function for the tightly-coupled Sepic converter. It is shown that the control-to-output function is just second-order, not fourth-order like the conventional Sepic converter . The coupling capacitor of the converter has no effect on the control, and it can be

The role of an uninterruptible power supply (UPS) is simple in concept: provide a temporary power bridge to support the load between the loss of the utility and the transfer to diesel generators. Even though the task is easy to define, the best way to achieve the goal is often clouded in obscurity as the benefits
