The low isolation capacitance of 3.5pF and the high 150kV/µs CMTI makes this part ideal for IGBT, Si-MOSFET, SiC, or cascode GaN isolated gate driver power supplies. The RxxCT(E) and RxxC05TExxS series are available in cut-tape (-CT) or tape-and-reel (-R) packaging options....
Offshore wind generation is generally more dependable than onshore wind. However, onshore wind turbines are less expensive, both in terms of construction and ongoing costs. The ideal solution could possibly be to locate wind turbines on an island to take advantage of the strong, regular off...
Chapter 20 Soft Switching A new Section 20.1 compares the turn-on and turn-off transitions of diode, MOSFET, and IGBT devices under the conditions of hard switching, zero-current switching, and zero-voltage switching. The material on quasi-resonant converters is unchanged. Coverage of multi-...
This article will focus on how a single-point power supply failure can lead to uncontrolled movements and examine how the robust construction of… August 29, 2024 by Chun Keong Tee Nexperia, Toshiba, and Navitas Expand MOSFET Product Lineups With an eye on efficiency, thermal resistance, an...
Test measurements necessary to support the choice of the optimum power MOSFET in terms of power dissipation, reliability and efficiency, include: Static characterization (breakdown, RDS(ON), leakage, etc.) Characterization based on bias and temperature conditions experienced by devices in the actua...
The standard 3-pin regulators are bipolar devices, but modern MOSFET-based devices exist, most of which are compatible with the “classic” regulators. We will be using three of those classic regulators today, a positive one, a negative one, and a variable (positive) one. ...
The main advantage of switched-mode power supplies is that they are standard linear regulators used by switch transistors or power MOSFET. This reduces the cost of electricity. This means that when the switching transistor is fully turned on and the current flows, the voltage drop is minimized ...
