Are you SiC of Silicon? - Part 1

Click image to enlarge

Anup Bhalla, Ph.D., Vice President Engineering, UnitedSiC

SiC applications began in the 2000s with the adoption of SiC JBS diodes into PFC applications. This was followed by the use of SiC diodes and FETs in the PV industry. But the recent surge in applications relating to EV On-board chargers and DC-DC converters is driving SiC growth. The nascent adoption in the

When Grounds are Separated

Click image to enlarge

How should you proceed with a switching regulator with an analog ground (AGND) and a power ground (PGND)? This is a question asked by many developers designing a switching power supply. Some developers are accustomed to dealing with a digital GND and an analog GND; however, their experience frequently fails

Figure 1. Boost topology for generating a high voltage from a low voltage

If a high voltage needs to be generated from a low voltage, a boost converter can be used. This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic topologies are the buck

Wide Bandgap Semiconductors and Packaging - it’s happening

Kevin Parmenter, Field Applications Manger, Taiwan Semiconductor

The promise of wide bandgap semiconductors (WBG) are higher switching frequency and higher operating temperatures perhaps smaller sizes, greater efficiencies and perhaps higher reliability, less size, less cooling – no fans for example, smaller heatsinks, smaller capacitors, less weight and overall better
