“…The presence of this component may cause distortion of the generated line current by the 3rd harmonic. The time scale, as well as the nature of the compensated phenomenon, enable the use of electrolytic capacitors as an energy storage system in comparison to systems where battery energy storage systems are used [23,24].…”

This paper presents a single-phase power filter with an energy storage bidirectional DC/DC converter, both of which are equipped with separate capacitor-based DC links that provides good transient response and reduce energy storage capacity. The device is dedicated to the compensation of active power surges generated by nonlinear loads characterized by intermittent operation, where the operating time of a device in relation to the idle time is relatively short. As a compensated and filtered object, the single-phase spot welding machine with a thyristor current controller was assumed. In the case of such devices, the feeder has to be dimensioned for the peak loads, which increase the cost of installation—due to the fact that the used components have to be oversized. The proposed solution can produce measurable economic benefits by reducing the rated power necessary to energize periodically operating loads and improve the indicators of electrical energy quality. An elaborated control algorithm based on a switchable control structure provides a fast and good transient response. The work contains a comprehensive analysis of storage sizing, confirmed by simulation results performed in the Matlab and Simulink environment. Based on the analyses carried out, the laboratory model of the device was implemented and experimental verification performed.

“…One of the most interesting and fascinating methods for compensating the volatility of electric supply is by using cascaded multilevel converter (MLC) based battery energy storage system (BESS) that comprises of CHB inverters [22]. The ability of the cascaded multilevel converter to utilize lower-voltage semiconductor switches makes it one of the most suitable topologies for BESS.…”

“…It lowers the THD and offers higher modularity compared to a typical inverter, thus contributing to a simpler voltage-scaling setup [23]. BESS, which is based on a three-phase CHB multilevel converter and uses lithium-ion batteries, was first proposed by [22]. By utilizing cascaded H-bridge inverters, BESS was found able to achieve positive performance operation while charging and discharging.…”

This paper presents proposal of a five-level LLC resonant DC–DC converter design procedure for battery chargers. The five-level inverter side of the proposed converter is connected to a transform-less LLC resonant tank to ensure operating at high frequency and achieve soft switching. The proposed converter has less weight, size, and cost. It is also much simpler in terms of implementation, and has smooth energy conversion to the load. The proposed converter is designed to work within the range close to the resonant frequency, to ensure higher power density and efficiency. Thus, the range of operating frequency is set to be (91 kHz < fsw < 110 kHz), while the LLC parameters is designed to achieve resonant frequency fr = 100 kHz. Therefore, it is designed to achieve zero voltage switching (ZVS) for all switches, which enhances the efficiency as well. The theoretical analysis outcomes were confirmed by simulation studies conducted using MATLAB/SIMULINK. An experimental model was also developed and validated with 100 VDC input voltage, which delivered output power of 100 W, 48 V, with efficiency around 96.9%. Selected findings are presented to confirm the effectiveness of the suggested converter.
