This paper presents a zeta/flyback hybrid converter with a PV array as its power source for an LED street light or digital signage application. When the PV array is used in a LED lighting system, it needs a battery charger and discharger. In order to increase the areas of application for different PV arrays, a zeta converter has been adopted as the battery charger. In addition, since a flyback converter has a simpler circuit, it is used as the battery discharger.

Abstract This paper presents a novel approach for feedback linearisation in a continuous conduction mode (CCM) of the flyback converter.

In order to reduce the transformer stray capacitance, the two windings must be wound on the opposite sides of the core.

Abstract:

The active clamp flyback (ACF) converter is gradually becoming popular in the application field of low or medium output power range due to its advantage of soft switching and high conversion efficiency. An asymmetric half-bridge (AHB) flyback converter has been proposed in previous studies. The main advantages of the AHB flyback are the same number of components as the ACF converter and the soft switching technique. In this paper, an AHB flyback converter with constant off-time (COT) plus pulse frequency modulation (PFM) is proposed, so that the resonant time is not affected by the input volta

Abstract:

This paper discusses two types of transformers 3 A and 5 A with the addition of a flyback converter circuit. The transformer 3 A is only able to lower the DC output voltage and cannot produce an AC output voltage. So that the addition of a flyback converter circuit is proposed to change the AC output voltage and increase the voltage based on the desired load. The results of the 3 A transformer test obtained an increased output voltage from 12.21 Vdc to 18.04 Vdc with a constant time period of 1 minute. While testing the 5 A transformer shows that the increase in output voltage is obtained by a

This study proposes a power factor correction (PFC) flyback converter, which uses film capacitors with longer lifespans instead of the existing electrolytic capacitor. Additionally, it adopts a coupled inductor and an LC resonance filter to mitigate the output ripple, which is inevitably generated by a film capacitor, and applies discontinuous conduction mode (DCM) for power factor correction. In contrast, this study measures the input and output voltages of the PFC flyback converter and the switching current for the DCM control and proposes a duty split method by adding a comparator and trian
