“…2. Although this topology is similar to other configurations found in the literature [11], [13], [14], this work explains a detailed methodology to perform a bidirectional Flyback with both operation modes and experimental results. By the integration of two different Flyback stages, one for each polarity of the line voltage, into a single two-polarities stage, input diode bridge can be avoided [11].…”

This paper presents a multifunctional bidirectional converter. The proposed converter works as a grid-tied inverter, injecting power coming from a PV subsystem to the AC mains in the daytime hours, but also supplies energy to a LED-based street lighting system at night. The topology is based on the integration of two Flyback converters thus allowing the desired bidirectional energy flux. Each Flyback has a different polarity, making energy flowing in both directions possible. A prototype was built in order to prove the feasibility of the proposed topology and experimental results are shown below. In rectifier mode, an efficiency of 86% was achieved while a 88.9% in inverter mode.

“…Because of its simplicity, it is commonly used for low power applications [8]- [9] and at the same time, researches are focus on its further modification. There are number of different flyback topologies [10] developed with different application level. This bidirectional flyback topology is derived from conventional DC-DC converter, it is an integration of two flyback converters which working in Discontinuous Conduction mode.…”

Power converters have great importance in this technically advanced world because many electronic devices use controlled source. Thus new converting topologies are developing to get better operation in terms of efficiency. This paper deals with a bridgeless flyback converter topology which have bidirectional power flow capability. This converter have great importance in the inverters for residential use because, a single converter can be used as AC-DC converter for battery charging and DC-AC conversion while battery discharging. Conventional flyback converter is modified to the proposed bidirectional flyback converter. It is an integration of two flyback converters. The steady state operation and its switching strategy were presented here. Bidirectional flyback converter has been designed with the requirement of 40W, 24 V output in rectification operation and inverting operation aims for the single phase AC voltage of 230V. A battery storage unit is charged by the flyback converter and is discharging through the same converter for the residential AC load, when there is no conventional supply. Matlab/Simulink model has also been developed and relevant results are also discussed in this paper. Simulation results show good correlation with theory.

“…This new approach, represented in Figure 3, has, inherently, a bidirectional power flow capability because, as it has been commented before, it avoids the use of the rectifying diode bridge. In fact, this operation mode has already been justified in the literature where an integrated topology for supplying lamps from a DC bus voltage with output AC (HID lamp) voltage is presented [12] and for hybrid systems [6] [13].…”

This work proposes an electronic driver for street lighting systems integrated to renewable energy. In recent lighting applications, the use of micro renewable generators in lighting points makes necessary the use of special electronics to handle the bidirectional energy flow in the ballast. The proposed input stage is a topology based on the integration of two flyback converters with different polarities, in order to avoid the use of the input diode bridge rectifying stage, allowing the converter operate with bidirectional energy flow. Thus, this system has two distinct operation modes. The rectifier mode is responsible to supply a street lighting system based on LEDs from de utility grid during the night, and the inverter mode must deliver energy into the power grid provided by a solar panel during the day.This work focuses in the inverter stage, which comprises a boost converter, responsible for the Maximum Power Point Tracking (MPPT), and a flyback inverter. The present topology is an alternative to standard bidirectional input stages, as it can be used to deliver energy into the power grid, due the avoidance of the input diode bridge.
