GaN ICs Wanted for Power, EV Markets


Circuits built with discrete GaN components may get the job done, but fully integrated GaN circuits remain the ultimate goal because they would offer many of the same advantages as integrated silicon circuits. These benefits include lower cost as the circuit footprint is scaled, and reduced parasitic resistance and capacitance with shorter interconnect runs. In addition, improved device perf... » read more

PCB Layout Tips For Low Side Gate Drivers With OCP


Our 1ED44173/5/6 are the new low side gate driver ICs that integrate over-current protection (OCP), FAULT status output and enable function. This high integration level is excellent for the digitally controlled Power Factor Correction (PFC) applications with boost topology and ground reference switching. In PFC applications, shunts are used to sense power switch current or DC bus current... » read more

Higher Creepage And Clearance Make For More Reliable Systems


Electrical and electronic applications must be designed to ensure human safety, as well as systems reliability from high-voltage conditions. Thus, the power semiconductors used must also fulfill these safety and distance standards set by organizations such as Underwriter Laboratories (UL) or the International Electrotechnical Commission (IEC). Even though the TO247 package has been widely us... » read more

Review on Driving Circuits for Wide-Bandgap Semiconductor Switching Devices for Mid- to High-Power Applications


Abstract: "Wide-bandgap (WBG) material-based switching devices such as gallium nitride (GaN) high electron mobility transistors (HEMTs) and silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs) are considered very promising candidates for replacing conventional silicon (Si) MOSFETs for various advanced power conversion applications, mainly because of their capabi... » read more

A Comparative Analysis of Computer-Aided Design Tools for Complex Power Electronics Systems


Abstract: "Companies working on semiconductors must currently assure the customers of not only the performance of the semiconductor device per se, but also its performance when it is implemented in a real board, therefore including the role of parasitic effects. It is therefore very important to evaluate, especially during the design phase, not only the single device, but the complete board ... » read more

SiC MOSFETs In The Landscape Of Modern Power Devices


Over the years, low losses possible by high breakdown field made silicon carbide (SiC) MOSFETs extremely popular amongst engineers. At present, they are mostly used in areas where IGBTs (Insulated Gate Bipolar Transistors) have been the prevailing component of choice before. But which role do SiC MOSFETs play in today’s landscape of power devices? With SiC MOSFETs (Metal-Oxide-Semicond... » read more
