“…The peak residual current (i R ), i Rpk , in the third operation stage (t R ) of the SEPIC PFC during DCM, is obtained when the input voltage reach its maximum value (t = ¼ or n = N/4), according to (21). 1 In the same way, the L 1 peak current presents a negligible difference for both topologies.

“…The SEPIC converter has two inductors and L eq is obtained from the parallel of both respective inductances. In this topology, P IN is controlled by changing the PFC equivalent inductance, L eq , according to (1), through the replacement of L 2 by the VI. In this topology, the SRPLI bus voltage at the PFC stage output will change and as consequence so will the FL power, P FL , thus satisfying the power balance between both PFC and SRPLI stages.…”

“…A self-oscillating command circuit (SOCC) is usually accepted as a low cost suitable solution [1], because of its good features as simplicity, robustness, absence of integrated circuits and auxiliary sources. However, due to inherent limitations, the use of the SOCC, in electronic ballasts (EBs) with special functionalities has not been widely discussed or reported in the literature.…”

This paper presents a new high power factor dimmable self-oscillating electronic ballast (DSOEB), in which a variable inductor (VI) is used to control the fluorescent lamp (FL) power. Two different approaches are proposed to provide a wide dimming range using a self-oscillating electronic ballast, and a power factor correction (PFC) stage. In the first one, the VI is placed in the series resonant parallel-loaded filter (SRPLI), controlling the rms value of the lamp current with the dc bus voltage supplied by the PFC stage in a closed loop, and in the second one, the VI is placed in the PFC stage, controlling directly the power feeding the inverter. Experimental results for both topologies are presented to evaluate the preliminary performance of the circuit for a 32 W FL.

This paper proposes a single-phase DC to AC inverter for ESG (electrostatic generators) that may be used in the household’s application. The electrostatic generators were developed a while ago and remained abandoned for a long time. Now, as the modern technology advanced, it’s time to utilize the ESG to power generation. A pulse width modulation (PWM) based high voltage DC to AC inverter is a suitable system for converting the EGS high electrostatic DC voltage into standard 50Hz, 220V(rms) AC. The PWM technique is used to control the inverter switches to create a pulse width modulated bi-phase square wave signal. A lowpass LC filter has been utilized to remove the higher harmonic frequencies and which is capable to reduce the total harmonic distortion (THD) around 3.5%. The proposed model showed the overall system performance in terms of efficiency is 95%. To use ESG, this inverter is an easy and cost-effective electrical device. From the result, it is observed that the output voltage of the proposed inverter is greatly improved compared to the other inverter circuits.

Power electronics and communication electronics are both based on electromagnetic theory, but they are usually regarded as two distinct subfields in electrical engineering. In fact, however, electric power is the most common matter-based carrier of messages; thus, power electronics and communications can be jointly considered. Here we study the essential nature of dc-dc power converters and characterize the similarity of their operation principle to that of communication systems. Based on this similarity and the double modulation methods used in power electronics and communication, a double modulation strategy for both power and data is presented and applied in dc-dc power converters to achieve what we call 'talkative power'. A modulation strategy called frequency hopping-differential phase shift keying (FH-DPSK) is also presented to overcome the crosstalk between chosen transmission systems. The proposed talkative power strategy sheds new light on and provides inspiration for the further development of power electronics and communication.
