“…For single-phase DC-AC converters, because of the simplicity and rugged control scheme, PWM inverters were the most commonly used power converter for decades in applications such as UPS, motor drive, and induction heating with lower voltage (below 1000 V) and lower capacity (below 5 kW) [115][116][117].…”

Because of the global trends of energy demand increase and decarbonization, developing green energy sources and increasing energy conversion efficiency are recently two of the most urgent topics in energy fields. The requirements for power level and performance of converter systems are continuously growing for the fast development of modern technologies such as the Internet of things (IoT) and Industry 4.0. In this regard, power switching devices based on wide-bandgap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN) are fast maturing and expected to greatly benefit power converters with complex switching schemes. In low- and medium-voltage applications, GaN-based high-electron-mobility transistors (HEMTs) are superior to conventional silicon (Si)-based devices in terms of switching frequency, power rating, thermal capability, and efficiency, which are crucial factors to enhance the performance of advanced power converters. Previously published review papers on GaN HEMT technology mainly focused on fabrication, device characteristics, and general applications. To realize the future development trend and potential of applying GaN technology in various converter designs, this paper reviews a total of 162 research papers focusing on GaN HEMT applications in mid- to high-power (over 500 W) converters. Different types of converters including direct current (DC)–DC, alternating current (AC)–DC, and DC–AC conversions with various configurations, switching frequencies, power densities, and system efficiencies are reviewed.

“…A zero-crossing detector is simple and easy to implement to obtain grid information such as phase angle by detecting the zero-crossing point of the utility voltages and is reported in [21], [22] as being robust to a small amount of distortion. Generated power by renewable energy systems, such as solar photovoltaic and wind energy, can be injected to the grid by means of power electronic converters.…”

A zero-crossing detector (ZCD) is one type of synchronization method. An impulse is generated by the ZCD circuit when the AC sine wave crosses zero. The width of this impulse circuit has a bad effect on the working of other circuits. The width of this impulse is dependent on the elements used. The circuit output will be studied by generating two complementary pulses for the inverter. ZCD circuit facilitates the integration of photovoltaic (PV) power systems with other systems. The proposed design can be a good choice to allow connection for different sources for certain loads. Such as in the case of isolated load or microgrid feed by different distributed generators, such as synchronous generator (diesel) and PV. There is a big challenge to choose high-quality elements of the ZCD circuit to generate the accurate impulse, leading to higher performance of the used system. So, this paper will study two elements. Transistor 2N3904 and optocoupler 4N27 are used and the obtained results are compared and analyzed to choose the suitable one. The system used is designed once based on the transistor and then with an optocoupler. Finally, the results obtained from the different designs are compared and analyzed. The proposed system is simulated based on Proteus software and the corresponding results are clearly depicted with detailed analysis and compared with an experimental prototype that is accurately created. It is found that there is a good agreement between the simulation and the experimental results, which inform the quality of the designed system.

“…In recent years, the development of secure, low-carbon, and renewable energy sources and various smart micro-grid systems [ 1 ], power converter-based system compensating devices [ 2 , 3 ], advanced power converters using state-of-the-art wide-bandgap (WBG) switching devices, and digital-integrated intelligent control schemes [ 4 , 5 ] have become very popular research topics in the field of electric power and energy engineering. To best facilitate the above-mentioned technologies, various types of power converters are normally required [ 6 , 7 , 8 , 9 , 10 , 11 ], whose main components are semiconductor power switches and various system control units. To further enhance and optimize the performance of power converters, advanced semiconductor switches based on WBG materials, also known as third-generation semiconductor materials, such as gallium nitride (GaN) and silicon carbide (SiC), are emerging as very promising solutions [ 12 , 13 ].…”

An energy storage system using secondary batteries combined with advanced power control schemes is considered the key technology for the sustainable development of renewable energy-based power generation and smart micro-grids. The performance of energy storage systems in practical application mainly depends on their power conditioning systems. This paper proposes a silicon carbide-based multifunctional power conditioning system for the vanadium redox flow battery. The proposed system is a two-stage circuit topology, including a three-phase grid-tie inverter that can perform four-quadrant control of active and reactive power and a bi-directional multi-channel direct current converter that is responsible for the fast charging and discharging control of the battery. To achieve the design objectives, i.e., high reliability, high efficiency, and high operational flexibility, silicon carbide-based switching devices, and advanced digital control schemes are used in the construction of a power conditioning system for the vanadium redox flow battery. This paper first describes the proposed system topologies and controller configurations and the design methods of controllers for each converter in detail, and then results from both simulation analyses and experimental tests on a 5 kVA hardware prototype are presented to verify the feasibility and effectiveness of the proposed system and the designed controllers.
