An Overview of Bidirectional AC-DC Grid Connected Converter Topologies for Low Voltage Battery Integration

Abstract

<p>Battery energy storage systems are becoming more and more popular solution in the household applications, especially, in combination with renewable energy sources. The bidirectional AC-DC power electronic converter have great impact to the overall efficiency, size, mass and reliability of the storage system. This paper reviews the literature that deals with high efficiency converter technologies for connecting low voltage battery energy storage to an AC distribution grid. Due to low voltage of the battery isolated bidirectional AC-DC converter or a dedicated topology of the non isolated converter is required. Review on single stage, two stage power converters and integrated solutions are done in the paper.</p>

Radiated emission from DC bus loop of AC induction motor inverter FEM based and experimental evaluation

“…The parasitic inductance of this path should be as minimal as possible. Simulation based optimization with goal to minimize this inductance has been carried out in many research papers [12]- [17], even motors with integrated inverter are proposed in the literature [18]- [20]. In several papers it is proposed simulation based determination parasitic inductances and capacitances [21]- [23].…”

Bidirectional Synchronous H6 Inverter for Hybrid AC/DC Distribution System With Improved Light Load Efficiency

“…Similarly, a two stage topology operates as a bidirectional inverter between the EV motor and battery whether the battery is being charged or the motor is being supplied to drive the EVs [8], [9]. When considering ESSs such as rechargeable batteries or ultra-capacitor systems, they should be able to provide rapid frequency control, load monitoring, and system enhancement capabilities [10]- [12]. Despite the fact that in most circumstances, only a unidirectional rectification mode is required to charge the EV battery, it is probable that bidirectional capability will be required in EV applications to facilitate V2G between the grid and DC-bus.…”

“…Awareness of human impact on the environment resulted in increasing use of renewable energy sources [1] that in turn contributed to the development of power electronics applications: interface converters for renewable energy sources [2], reversible converters for energy storage systems [3]. Moreover, standards that govern the quality of electrical energy consumed from the network forces to use more efficient power supply blocks with utilisation of power factor correction schemes.…”
