Power supply is an electronic circuit that is used for providing the electrical power to appliances or loads suchas computers,machines,and so on. These electrical and electronic loads require various forms of power at different ranges and with different characteristics. So, for this reason the power is converted into the required forms (with desired qualities) by using some power electronic converters or power converters.

Electrical and electronic loads work with various forms of power supplies, such as AC power supply, AC- to-DC power suppl ....etc

Server push or push technology is an Internet-based communication style in which the request for a given transaction is initiated by the publisher or the central server. It contrasts with pull / get, where the request for transmission of information is initiated by the receiver or client. Push services are often based on information preferences expressed in advance. This is called a publication / subscription model. A client subscribes to various channels of information provided by a server; Whenever new content is a ....etc

Good day

I am looking to verify my understand of the timing of the push-pull PWM mode of the dsPIC30F1010.

I am looking to have the pulse width incremental by 50ns. From my understanding this would equate to Fosc of 1.25MHz. 50ns = 1/(1.25MHz x 8 x 2). Eight being the frequency divider after the PLL and two being used since the input the PWM module is effectively doubled in frequency due to the clocking using the rising and falling edge for counting? Does this thinking make sense?

I calculate a maximum period of 3.2768ms. (2^1 ....etc

I am a BSEE with extensive (>25 years) industry experience in power supply project and program management but without specific design experience in switch mode power supplies (SMPS). I now need to qualitatively gain a better understanding of the various SMPS topologies. The http://seminarsprojects.net/Thread-seminars-report-on-smps is the correct level of information I am looking for. Is a similar seminar available to be attened in the USA (preferably West Coast) and if yes, what is the schedule and cost.

SEMINAR REPORT ON SMPS
Presented BY
PRIYANKA N.
VIDYA VIKAS INSTITUTE OF ENGINEERING AND TECHNOLOGY

INTRODUCTION:
SMPS i.e. Switch Mode Power Supply, before starting to introduce this topic we first have to
know what power supplies are
Power Supply: A device for the conversion of available power of one set of characteristics to
another set of characteristics to meet specified requirements.
Conventional series regulated linear supplies maintain a constant voltage by dissipating excess
power in ohmic ....etc

A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power), to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation ....etc
