“…Similar to current loop, voltage control loop is also represented in per unit format and both ADC and DPWM gains could be taken as unity. Now voltage loop function ( 16) could be expressed, using (19) and (20) as: 𝑇 𝑣 (𝑠) = 𝐺 𝑣𝑖𝑙 (𝑠) × 𝐺 𝑣𝑐 (𝑠) × 𝐾 𝑉0 × 1 𝑉 𝑖𝑛 × 𝐾 𝑉𝑖𝑛 × 𝐾 𝑖𝐿 (21) For ideal sinusoidal current reference generation techniques, input feedforward term will be unity. Thus, equation ( 21) could be adapted as:…”

Rise in use of electronic gadgets and rapid electrification of automotive sector is leading to increase in number of equipment connected to the power grid. Switched mode power supplies are commonly used to power up the electronic equipment in the view of compact size and best efficiency. Total harmonic content injection to the grid is required to be under the limits set by the international standards to ensure the highest power quality. Power factor correction technique is largely adapted as front end in majority of power supplies to regulate the Total Harmonic Distortion and to achieve highest power factor. In addition, it is required to limit the input current drawn from the power socket as prescribed by the international standards in order to get commercial license. In this paper, design investigation of digitally controlled interleaved converter with input current limiting is discussed. Mathematical modelling of the CCM operated interleaved PFC is carried out along with controller design approach with nonlinear voltage loop control is presented. Two current limiting techniques based on type of digital control technique employed in the PFC are investigated and results are analyzed. Simulation model of the system is developed and simulation results are supported and verified with hardware implementation and validation.

“…In [355], the authors proposed a modified SEPIC LED driver (Figure 37a) that allows the lower voltage stress operation, enabling the use of lower voltage rated semiconductors compared to other buckboost derived topologies, keeping an equivalent performance when compared with the conventional boost topology. In [357], a single-stage flyback PFC converter is proposed for flicker elimination. Additionally, in [358], a PFC topology based on the flyback converter is presented.…”

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.
