“…Radio-based time sources like global satellite navigation systems are commonly used and provide precise time. To avoid the requirement of dedicated GPS receivers for each individual device, time distribution systems such as the Network Time Protocol (NTP) [1] or IRIG-B are used. Whereas NTP was already specified in IEC 61850 [2] as time distribution mechanism, it is only suitable in applications for which a time synchronization accuracy in the milliseconds range is sufficient.…”

-In distribution section of power system the power synchronizing and power factor rectification is a main factor analysed by the survey report to decrease the commercial as well as technical loss occurred in power distribution. The commercial loss is that whenever the power get lost by manufacturer, the distributor has to paid the power loss amount to the industrial subscriber through law of justice, in order to overcome this with the help of technical and commercial support, this project helps a lot. In this project the delay time of manual synchronization which is 1 to 2 hrs. can be reduced to 3-4 second as well as the power and cycle losses occurred in distribution after synchronization can be rectified by auto stabilizing method and regenerating of pulses so that losses can be vanished and continuity of power supply can be maintained. This system can also be implemented whenever 3, 4 feeder are connected simultaneously for power feeding in hospitals, bus stand and government sector etc.

“…Although the circuits [29]- [31] lack a unity power factor, they comply with IEC 61000-3-2 [26]. A family of such circuits was described in [23] and [24]. In this family a boost circuit accompanied by a DC/DC converter was introduced to form the so-called single-stage single-switch AC/DC converters.…”

“…Many studies have examined the relevant issues and numerous topologies have been proposed. The proposed solutions of these studies can be classified into two groups: those designed such that the input line current is sinusoidal and those designed such that it is non sinusoidal [23], [24]. The group of topologies with the sinusoidal line current almost achieves the requirement of unity power factor but requires a complex topology or control circuit [25], [26].…”

Abstract-New recommendations and future standards have increased the interest in power factor improvement circuits.There are multiple solutions in which line current is sinusoidal. In addition, in the recent years, a great number of circuits have been proposed with non sinusoidal line current. In the proposed circuit, the power factor is improved by using an auxiliary winding coupled to the transformer of a cascade DC/DC fly back converter. The auxiliary winding is placed between the input rectifier and the low-frequency filter capacitor to serve as a magnetic switch to drive an input inductor. The proposed approach is primarily based on the concept of inductive effect, from which PFC cells composed of energy buffers and high-frequency signals are introduced. Since the DC/DC fly back converter is operated at high-switching frequency, the auxiliary windings produce a high frequency pulsating source such that the input current conduction angle is significantly lengthened and the input current harmonics is reduced. Properly selecting an eligible PFC cell and inserting it in between input rectifier and dc-link capacitor can yield an SSC which can improve the input power factor significantly.

“…In bridgeless PFC converters, the PFC converter is combined with input rectifier diodes. The schematic of a bridgeless PFC converter is shown in Fig.1 (b) [3][4][5][6][7]. The other method is the so-called single stage PFC converter (S 2 PFC).…”

Based on the standards that limit the harmonic pollution of electronic systems, the use of PFC converters is mandatory. In this paper, a new resonant bridgeless PFC converter is introduced. By eliminating the input bridge diodes, the efficiency is improved. Moreover, soft switching conditions for all of the semiconductor elements are achieved without adding any extra switches. As a result, high efficiency is attained. The proposed converter is analyzed and the theoretical and simulation results of the proposed converter are presented. In order to verify the validity of the analysis, a 40 w prototype converter is implemented and experimental results are presented. The experimental results show that high efficiency is attained while achieving a high power factor.
