Corona in switching power supplies

Proceedings of APEC 97 - Applied Power Electronics Conference, 2002
Design literature for dealing with corona in switching power supplies for aircraft or in lamp ballasts does not contain the effects of the switching frequency on corona inception or extinguish voltages. Test data is presented showing these effects. Design techniques for corona are also discussed.

Switching Power Supplies: Analysis of waveform distortion and absorbed powers

2007 9th International Conference on Electrical Power Quality and Utilisation, 2007
Analyses to have a quantitative idea of the real behavior of Switching Power Supply (SPS) units from the point of view of waveform distortion and power absorption are developed. Results of several experimental tests performed by means of a test system built up at Laboratories of the Second University of Naples (Italy) are firstly reported.

Switch mode power supply scalability

2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2008
As the requirements for electronic inside home appliances are growing, many electronics control boards are being developed to increase the output power. A good way to reduce the number of electronic boards developed is using switch mode power supplies, which can delivery a wide range of output power using the same topology.

Flyback Switching Power Supply Using FAN6754A

2019
Switching power supply (power adapter) is used to convert high voltage alternating current into low voltage direct current. Pulse-width modulating (PWM) is one of the most popular methods to design switching power supply. In order to control the output signals, the duty cycle of the fixed pulse period can be changed by PWM to make the MOSFET tube on or

Research on 5V Internal Power Supply Circuit of Switching Power Supply

Applied Mechanics and Materials, 2014
In order to guarantee the stability working of internal circuit of switching power supply, an internal power supply circuit with stabilization output was designed in this paper. Based on the voltage stabilization principle of zener diode, the internal power supply circuit put the high input voltage into 5v output voltage.

Experimental chaos in switched power supply

SPIE Proceedings, 2010
Chaos was observed in a specific kind of switched stabilized power supply. It emerged from pulse iteration circuit. In the paper conditions for emerging of chaos are presented and bifurcation curves are shown. Pulse stabilized power supplies have been the frequently used kinds of power supplies for many years. Many kinds of curves are used.
