Here we’ll show how Spice can be used to provide proximity loss results for magnetics windings. Proximity loss equations are solved for a set of frequencies, and a simulation circuit is generated which predicts the proper AC losses regardless of the current waveform.
Inductor winding AC
It should come as no surprise to anyone that a the continuing adoption of Digital Power System Management (DPSM) within the communications and computer industries continues to be driven, in large part, to the high current levels demanded by the sub-20nm ASICs and/or FPGAs that are at the core of their
In response to Google’s Little Box Challenge (LBC), our Virginia Tech team, the Future Energy Electronics Center (FEEC), decided to design a power inverter. As shown below, our design significantly surpassed the LBC specifications.
Our final design exhibited a power density of 61.2 W/in3,
Industrial automation systems are undergoing a revolution to reduce latency and down time. This directly translates to increased profits for factory operators and machine builders. Dubbed Industry 4.0, this effort will add more intelligence across the factory floor from HMI panels and controllers to communication
Smaller, smarter, and more powerful are market trends for low-power switched-mode power supply (SMPS) applications. Smaller requires the SMPS to have a more compact form factor – and, thus higher power density. Smarter requires intelligent system-to-system/system-to-human communication to ensure the systems
Measuring the resistance of something is a great deal more complicated if that resistance is very small. With bigger resistances, measurements can be as simple as connecting two leads between a digital multi-meter (DMM) and the device under test (DUT) and reading the number. With small resistances, the multitude
Thermal behavior is important to determining the lifetime performance of electronic system design and the power supply is a critical element in determining that behavior. Heat has a number of effects on a system. The most problematic at a system level is one of long-term reliability. High operating temperatures
In the last few years GaN based devices, both discrete FET’s and MMIC’s, have been released and widely used in high power microwave amplifier systems. These devices, available from several foundry sources, are typically fabricated on 100mm SiC wafers. GaN on Si processes are also under consideration,
This software, in combination with Rigol oscilloscopes (series DS/MSO2000A, DS/MSO4000 or DS6000) allows customers to set up small test systems, which represent a reasonably priced alternative for measuring switching power supply parameters during the development phase.
