Special Issue Information

Dear Colleagues,

World growing population creates the need of paramount efficient and sustainable, handling of energy. Power electronics has enabled efficient use of energy, and its techniques continue to expand its already large field of influence. Examples of its penetration are already present in ubiquitous equipment such as laptops and cell phones, rendering continuous improvement in rapid and lasting charges, also in new repeaters technologies like 5G, in finance with bitcoin mining, data centers in general, gaming industry, and space exploration. It is clear the impact on transportation with the continuous growth of electric vehicles (EVs). The last decade has seen an accelerated and remarkable insertion of power electronics into traditional power systems with solar and wind generation, storage, transmission, and distribution.  This Special Issue is about the inroad that power electronics plays challenging traditional energy approaches that still prevail in some fashion and pushing to new horizons. Topics of interest for publication include but are not limited to:

  • Ultra-efficient converter for microelectronics.
  • Advanced application in power systems, including generation, transmission, and distribution.
  • Residential power applications including lighting, high-efficient air conditioning, and water heaters
  • Solid-state transformers
  • Energy storage, including new batteries, controls, and PHM (Prognostic Health Management) techniques.
  • Converter for telecom especially for 5G applications
  • Power wireless transmission
  • Power electronics in transportation including charging station
  • Special power converter for emerging fields

A novel modular Transformerless, Self-balanced, Static Synchronous Series Compensator (TSB-SSSC) capable of delivering ultra-high current, with the objective of dynamically balancing the impedance of the transmission power grid, is proposed. Balancing transmission lines is crucial in power optimization and delivery because it increases the power transfer capability without building new power lines. The transformerless SSSC needs to support and control the line current from a few hundred to several thousand amperes. This paper presents how the ultra-high current architecture of the TSB-SSSC is achieved by operating multiple converters with self-balancing capabilities in parallel. The mechanism of self-balancing is based on the intrinsic physics of the capacitor and is enabled by a passive network of capacitor equalizers that keep the capacitor voltage equal during switching disconnection. The second self-balancing system consists of an inductive component that balances possible differences among delay switching caused by the aging of the multiple IGBTs from the different converters that form the SSSC. This work presents the analytical set of equations that describes the system and a complete set of simulations where the effectiveness of self-balancing paralleling topology is shown. Full article

With regard to DC/DC buck converter applications, the objective of this study is to expand the admissible range of the output voltage cut-off frequency while lowering the steady-state current cut-off frequency as possible. This study fortifies the inner loop by incorporating the novel subsystems such as an auto-tuner (for the dynamic current cut-off frequency) and active damping injection invoking the pole-zero cancellation nature with the particular designed feedback gain structure. The outer loop active damping control renders the closed-loop speed transfer function to be a first-order low-pass filter with the cooperation of the specially structured design parameters; in addition, it provides time-varying disturbance attenuation. The experimental results obtained for a 3-kW buck converter validate the feasibility of the proposed technique by showing a 34% performance enhancement (at least) compared with the recent active damping controller.

This paper presents a novel output voltage regulator in the cascade structure under the consideration of both the parameter and load uncertainties. It leads to the first-order closed-loop inner and outer loop dynamics in the low-pass filter form by the pole-zero cancellation through the active damping injection, which is the main contribution of this study. Moreover, it is proved that the active damping injection level determines the disturbance rejection capability of the closed-loop system. A 3-kW DC/DC boost converter confirms the actual advantages from these two contributions. Full article
