“…The control of linear regulated power supply is simple where as the control of SMPS is complex [5] as it requires the feedback network to generate the control voltage which decides the on time period of switching device [6] in the SMPS. So from the above discussion, it can be concluded that for most compact and most efficient applications [7], [8] the SMPS is preferable than the linear power supply.…”

In this paper, design and implementation of Switched mode power supply is analysed for various alterations of the supply voltage. Proper components were selected and its functionality was verified in NI-MULTISIM as a simulator. At first open loop configuration was designed, implemented and its functionality was examined in NI-MULTISIM. To examine the performance of the proposed system, PI controller is embedded using PWM based feedback network, and successfully verified in NI-MULTISIM

Harmonics reduce power quality and increase inefficiency. Although light emitting diode (LED) bulb has been considered more efficient than previous bulb technologies; its internal circuits potentially generate additional problems. This paper has surveyed 6 LED bulb samples and measured the harmonics generated by the internal circuits. As a result. 7 Watt type B LED bulb produces the highest 3rd order harmonics current which is incompatible with IEC61000-3-2 Class C. A prototype of LC filter is designed to decrease the harmonic level. The measurement shows that the designed passive filter is able to reduce at least 81.3% of harmonics.

“…Although dead angle does not exist in this structure, but in comparison with buck‐boost structure, its THD is higher and also number of the magnetic elements is more than other structures. In [27] half‐bridge series resonant converter is used as the DC‐DC converter and use coupled inductor as the current shaper. Although it has soft switching and there is no dead angle problem but like structure in [9] two switches are used.…”

Here, a new single stage single switch soft switching PFC (power factor correction) converter is presented and analysed. The proposed converter combines buck AC‐DC converter and forward DC‐DC converter and applies an auxiliary circuit to eliminate input current dead angle. Furthermore, soft switching is attained and switching losses are eliminated resulting in high efficiency. Another merit of the proposed converter is the partial direct transmission of input power to the output that helps to improve efficiency. Experimental results are presented which justify the above mentioned points and show less than 5% THD in the nominal load. Comparison with other similar single stage PFC converters is performed and shows the proposed converter provides the lowest THD while high efficiency is attained.
