A novel power MOSFET switching-mode power supply
International Journal of Electronics, 1985Increasingly, the operating frequency of switched-mode power supplies (SMPS) eliminates the need for bulky magnetic and output filter components, thereby reducing their overall weight and volume. Power MOSFETs, which are capable of operating at much higher frequencies than those achievable with present-day bipolar transistors, have by now established ...

A Small Power Switching Mode Power Supply Based on TOP Switch
2009 International Joint Conference on Artificial Intelligence, 2009In designing low power switching mode power supply (SMPS), its functions, tech-parameter and cost should be considered at the same time. TOP Switch has stronger functions than the discrete components. It is easy and flexible to design SMPS based on TOP Switch and the products always get less cost. SMPS based on UC3842 or UC3843 is compared with the one

Switched-Mode Power Supply for Control System
2019 6th International Conference on Control, Decision and Information Technologies (CoDIT), 2019Switched-mode power supplies (SMPS) are confidently replacing outdated linear power supplies. They are distinguished by high performance, improved stabilization indicators and compactness. The SMPS are widely used in power supply of control systems for small energy facilities. The article is devoted to the research of forward converter parameters.

Trends in Switch-Mode Power Supplies
INTELEC '87 - The Ninth International Telecommunications Energy Conference, 1987Size reduction of the dc-to-dc converter is most important issue in the switch-mode power supply. This paper presents general technologies and trends of high frequency switching of the dc-to-dc converter for the size reduction. Especially we discuss the problems of the magnetic amplifier as a highly reliable PWM element, when increasing the switching ...

Sliding Mode Controller for Switching Mode Power Supply
2010Switching Mode Power Supply (SMPS) is a nonlinear system in nature, for which the performance of linear control strategy is constrained. Therefore, this paper presents a sliding mode controller for SMPS. Due to its simplicity and robustness against parameter variations and disturbances, Sliding Mode Control (SMC) has been widely used in DC-DC power ...

METHOD FOR CONTROLLING A SWITCHED-MODE POWER SUPPLY AND A SWITCHED-MODE POWER SUPPLY
2001In order to reduce switching losses, the frequency of a switched-mode power supply is lowered, in the instance of a diminishing output load, by frequency changes which can, however, cause disturbances, e.g. a corruption of the image geometry in television receivers.

Transductor-regulators for switched-mode power supplies
IEEE Transactions on Magnetics, 1980In 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, 1986This 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, 2003In 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.
