High active mode efficiency switching mode power supply
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008Power supply standby mode efficiency has attracted much of the focus in the past years. However, larger total energy use and energy savings opportunities were in power supplies' active mode [1]. Recently, higher active mode efficiency was required and the 80 PLUS program has become one of the specification of ENERGY STAR.

APPLICATION OF SLIDING MODE CONTROL TO SWITCH-MODE POWER SUPPLIES
Journal of Circuits, Systems and Computers, 1995Switch-mode power supplies represent a particular class of variable structure systems (VSS). Thus, they can take advantage of non-linear control techniques developed for this class of systems. In this paper the so called sliding mode control is reviewed and its application to switch-mode power supplies is discussed.

A self-powered supply circuit for switching mode power supply
2017 IEEE 12th International Conference on ASIC (ASICON), 2017The paper presents a self-powered supply circuit for high-voltage switching mode power supply (SMPS), such as buck or flyback. It can make whole SMPS converters more efficient. The proposed supply circuit is realized by the energy recycling of power MOSFET switching procedure. Firstly, dV/dt at the drain terminal of power MOSFET is detected.

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.
