Enabling Solar and Renewable Energy Power Conversion with SiC

2021-02-22T13:53:52-06:00February 22nd, 2021|Categories: Article, Featured, Wolfspeed|

by Guy Moxey, Senior Director Power Products, Wolfspeed Essential renewable energy solutions such as wind and solar power, often paired with energy storage, are one of the fastest-growing sectors in the industry, and wide-bandgap silicon carbide (SiC) technology is at the core of these solutions. End-system designers have established that SiC power semiconductors enable solutions

Technical Article: Selecting dc-link capacitors for inverters

One key factor: Determining the nuances of how capacitors handle expected ripple currents Examine a dc link capacitor’s ac ripple current and you’ll realize it arises from two main contributors: the incoming current from the energy source and the current drawn by the inverter. Of course, capacitors cannot pass dc current; thus, dc current only

Technical Article: The Junction Temperature Estimation of SiC MOSFETs in a Three-phase Voltage Source Inverter

2021-02-15T14:51:09-06:00February 15th, 2021|Categories: Article, Featured|

Junction temperature is the key point in power semiconductors and it should be maintained under standard limits. During the operations, the temperature of the junction is either estimated or unknown, that is why designers have to keep huge safety margins. Now, to measure the temperature of power devices, different techniques have been developed. One method

Evaluation of 1200 V, 300 A, SiC MOSFET Switching Performance

2021-01-21T15:03:35-06:00January 21st, 2021|Categories: Article, Featured|

The use of SiC MOSFETs has been increased in modern industrial applications due to fast switching, conduction loss, and an increase in breakdown voltage. With the ease of most rapid switching speeds and higher-frequency empowerment, the framework reduces the size and increases system efficiency. High-power SIC MOSFET modules are the acceptable substitution of Si IGBTs

Gaining the GaN advantage is easier than ever

2021-01-13T18:00:06-06:00January 13th, 2021|Categories: Article, Featured, GaN Systems|

The increasing popularity of GaN solutions in power electronics has prompted many companies to rethink the way they build their power systems. In the last few years, GaN has proven to be reliable and pushing the boundaries in smaller, lighter, and more efficient power systems in data centers, automobiles, consumer electronics, renewable energy systems, and

“GaN Is Like a Ferrari:” How GaN Is on the Fast Track for 2021

2021-01-04T18:00:19-06:00January 4th, 2021|Categories: Article, Featured, GaN Systems|

2020 ushered in a wave of GaN transistors in applications from automobiles to audio amplifiers. We talked with GaN Systems CEO Jim Witham to find out why he thinks 2021 could see even more GaN adoption. While gallium nitride (GaN) transistors were once the musings of university research projects 20 years ago, these devices are

Powered by GaN: Philips SPS2316G/93, 2C1A 65W GaN Charger
