Transductor-regulators for switched-mode power supplies

IEEE Transactions on Magnetics, 1980
In switched-mode power supplies the problem of stabilizing two or more output voltages often arises. Since with pulse-width modulation of the switching power transistors only one output can be exactly regulated it is necessary to restabilize the other outputs with additional regulators. For this particular case, transductors have been developed with an

Switch Mode Power Supplies with Idealised Performance

INTELEC '86 - International Telecommunications Energy Conference, 1986
This presentation discusses the requirements of the Switch Mode Power Supplies (SMPS) employed by British Telecom for their System X telephone exchanges. The power plant is of the non-distributed type and the requirement is for rectified power packaged in light weight small dimensioned rectifier modules where the techniques of switch mode are ideally ...

Reducing EMI in switch mode power supplies

10th International Telecommunications Energy Conference, 2003
In general, as the operating frequency of a switch-mode converter increases, the task of EMI (electromagnetic interference) suppression becomes more difficult. Many times, a reduction in power supply size is negated by bulky input and output filters. Additional mechanical and printed circuit board design iterations have resulted due to EMI difficulties.

MULTIMODE SWITCHED-MODE POWER SUPPLY

2001
A multimode switched-mode power supply operates in a first control mode when the output power supplied is lower than a predetermined value, and in a second control mode when the output power supplied is higher than said predetermined value. The switched-mode power supply comprises a series arrangement of a switch (S1) and an inductor (L; Lp), the ...

Ferrite materials for switched mode power supplies

IEEE Transactions on Magnetics, 1981
The major growth in the production of ferrite cores in recent years is due to a considerable increase in the use of switched-mode power supplies. After summarizing the main types of cores most utilised for this application, the author sets out the main characteristics generally required of ferrite materials.

SWITCHED-MODE POWER SUPPLY AND DISPLAY

2001
The invention relates to a switched-mode power supplying for a varying load in consecutive cycles of an operation period. Such a varying load may be, for example, a liquid crystal display device. The switched-mode power supply comprises converting means for converting an input voltage into an output voltage and control means arranged to generate a ...
