Bridgeless Power Factor Correctors (PFC) with a controller utilizing rectified ac variables can benefit from well-established strategies and circuits employed in PFCs with diode-bridge front-end. The grid voltage polarity is detected to compute the rms value of the grid voltage, and also used to generate and route the gate signals for the power devices. However, depending on the implementation, grid voltage disturbances may propagate through the polarity detection and RMS calculation stages, leading to a degradation of the input current and output voltage. This issue is addressed in this manuscript by investigating a single-phase bridgeless totem-pole (TP) PFC through simulation and proposing the replacement of the conventional implementation with a frequency-locked loop (FLL) to enhance the converter dynamics.

With the proliferation of power electronic (PE)-based resources in the electric grid, there have been numerous different kinds of simulation models developed and studied to understand their dynamic behavior. Study of PE-based resources using each simulation model has its own distinct advantages and disadvantages. Therefore it is very important to carefully select the appropriate model for the evaluation of the PE-based resources. In this paper, one such effort is made to analyze the different types of models in the case of a multi-port autonomous reconfigurable solar power plant (MARS). The MARS integrates a hybrid photovoltaic (PV)-energy storage system (ESS) plant to high-voltage direct current (HVdc) system and transmission alternating current (ac) grid. The dynamic models are evaluated under different test cases varying the short-circuit ratio (SCR) and control algorithms. Recommendations are provided on the equipment study needs based on the analysis completed.

Modular power conversion offers many technical and economic advantages as long as power sharing between modules is maintained. Power sharing through decentralized control (requiring no communication between modules and no central controller) offers the greatest flexibility. A droop-less decentralized control strategy has recently been demonstrated to achieve modular power sharing by incorporating nonlinearity in the integrator term in the control loop. This paper experimentally investigates the application of this control to input-parallel-output-parallel (IPOP) converters with buck output stages. It is found that converters with voltage-source-like characteristics at dc (such as voltage-mode CCM buck converters) require special consideration compared to other converters. The paper also explores the effect of this control on transient response. These features are demonstrated experimentally for voltage-mode and current-mode buck converters, including the effects of module-to-module variability.

In this paper, interpolation methods to enable fast simulation of photovoltaic (PV) inverters are proposed. The interpolation methods are based on the event-driven interpolating method that can be introduced in the simulation model to run the model at a higher timestep while maintaining accuracy. The proposed methods are tested on a neutral point clamp (NPC) converter and a two-level converter (2LC) that are typically used in large-scale PV plants. The interpolation methods are integrated into the NPC and 2LC simulation models in PSCAD/Fortran and RSCAD C platforms. These models are tested at different simulation timesteps in off-line and real-time simulation platforms PSCAD and RSCAD respectively.

Planar magnetics are being actively explored in a wide range of power electronics applications, with argumentation of their low cost being a key aspect of their popularity. However, unlike conventional wire wound magnetic components, their costs do not scale convincingly with volume owing to a strong dependence on manufacturing complexity. This paper assesses the cost factors impacting the design of planar magnetic windings. This is done qualitatively, through direct manufacturer survey, and quantitatively by presenting a cost modelling approach derived from cost quotations of exemplar planar transformers. The developed model fits excellently to the data it was trained on (6.5% error). It is shown to have good predictive power on designs that are well-represented by the training data (though not in the training set, 13% error), and reasonable performance (20-58% error) on designs which have limited representation in the training data.

The multiphase series capacitor buck (SCB) converter is an attractive candidate voltage regulator module (VRM) in point-of-load (POL) applications. However, there needs to be more discussion on the control issue and technique to achieve the fast-transient requirement for the SCB converter. This paper discusses the voltage stress and oscillation issue in the SCB converter when applying the phase overlap transient improvement control. A partial phase overlap transient control with simple implementation is proposed to achieve good transient performance while maintaining the device voltage stress and avoiding flying capacitor voltage oscillation. The simulation and experimental results under load step-up transient show the effectiveness of the proposed control.

This paper uses the averaged switch modeling method to derive the small-signal model of multi-inductor hybrid (MIH) converters. While modeling complementary switches with DC-coupled transformers is enough for conventional converters, the models for the hybrid converters need additional modifications to reflect the actual converter behavior accurately. To demonstrate the modeling and analysis technique, the generated models of four example MIH converters successfully capture the higher-order transfer function characteristics by their higher number of inductors and capacitors. The result provides corroborated analytical proof that MIH converters behave similarly to the multi-phase Buck converters, while the flying capacitors contribute to pole-zero doublets that create minimal impact on the converter operation.

This paper investigates the utilization of a planar Rogowski coil located between the dc-bus traces to measure the half-bridge’s switching transient current. The sensor’s fundamentals are explained, and design considerations are derived from a comprehensive parametric study analyzing the impact of a non-uniform dc-bus current distribution on the sensor’s mutual inductance. A compact current sensor prototype is designed and fabricated for a SiC MOSFET half-bridge application. Simulations show a minimal increase in the current communication loop stray inductance of 399 pH. The current sensor’s performance is experimentally validated with double pulse tests.

The paper presents a composite converter-based LED driver fed by an automotive battery and capable of delivering a constant current to an LED string. A two-stage architecture is proposed consisting of a composite boost converter in the first stage, cascaded with a buck converter in the second stage, which acts as a constant current source for the LED string. The composite boost converter consists of a capacitively coupled transformerless dual active bridge (CC-DAB) module and a partial-power boost converter module connected in an input-parallel output-series (IPOS) configuration. It is capable of processing indirect power efficiently, thereby reducing the device voltage and current stresses, resulting in higher overall efficiency compared to a conventional boost+buck automotive LED driver architecture. Furthermore, the CC-DAB module uses series capacitors to couple the inverting and rectifying bridges and eliminates the need for an isolation transformer, further improving efficiency and power density compared to a conventional transformer-based design. The composite converterbased LED driver is able to operate over wide input (8V to 18 V) and output voltages (3V to 50 V) driving a string of 1 to 15 LEDs. The experimental results show a maximum efficiency of 94.7% and significant efficiency improvements over the reference boost + buck architecture over the entire operating range.

Wave Energy Converters (WECs) are a form of renewable energy that harvests energy from the waves in a large body of water. WEC systems contain both a mechanical and electrical power take-off (PTO). The systems’ mechanical PTO has been theoretically been optimized to absorb the maximum energy in the wave environment. Still, the electrical PTO of WECs has not yet been optimized to maximize power conversion. The optimal bus voltage and switching frequency of the inverter to maximize energy conversion remains largely unstudied. This study uses Typhoon HIL real-time software to model the mechanical and electrical systems of a WEC operating in an irregular wave environment. The switching frequency of the inverter and the bus voltage is varied to determine the optimal operating conditions for the electrical PTO of the WEC.
