“…Once the sending coil frequency f o is set to 100 kHz, the switching frequency can be determined to 50 kHz in accordance with the time-sharing principle. Hence, the loaded resonant frequency f r is selected to 86 kHz with consideration for (8). The sending and receiving coils are implemented with Litz wires (44 twists / 7 bundles of 0.2 mm 2 cross section).…”

“…In contrast to the WBG-based active switches, SiC-Schottky Barrier Diode (SBD) technology has been disseminated into the wide areas of switch-mode power converter applications by now, featuring the low forward voltage, excellent thermal characteristics and reverse recovery-less operation [8]. Therefore, the hybrid power module of a high-speed Si-IGBT and SiC-SBD is a future promising power device for automotive and industrial power converters as well as home appliances and consumer electronics.…”

This paper presents a time-sharing frequency doubler principle-based current-fed zero current soft-switching (ZCS) high frequency resonant (HF-R) inverter based dc-dc converter for inductive power transfer (IPT) systems featuring a Silicon (Si) and Silicon Carbide (SiC) hybrid power module. The newlyproposed resonant dc-dc converter is suitable for producing a higher frequency resonant current with switching power loss reduction by the effect of a high speed punch trough Si-Insulated gate bipolar transistor (IGBT) and low-forward voltage SiC-Schottky Barrier Diode (SBD). In order to continuously regulate the output power, resonant current phasor control based on phase shift modulation (PSM) is newly applied. The performances of the newly-proposed IPT resonant power converter are demonstrated by experiment, after which the feasibility of the circuit topology and control method is discussed from a practical point of view.

“…YNCHRONIZING CIRCUITS are essential to grid connected power electronics equipments, namely on those related with power quality applications, where they can be applied to help identifying power quality events [1]- [5]. Basically, synchronizing circuits are applied in control algorithms of active power conditioners, such as active power filters [6] [7], uninterruptable power supplies [8][9] [10], dynamic voltage restorers [11], power factor correction converters [12] [13], EV battery chargers [14] [15], and grid interface of renewables [16][17] [18]. These applications are, increasingly, considered in the context of micro-grids, where the harmonic propagation and the dynamic phase deviation occurs frequently [19] [20] [21].…”

This paper presents a comparative analysis between two distinct synchronizing circuits, which are usually applied as the core of control algorithms for single-phase power quality applications. One of these synchronizing circuits corresponds to a single-phase Phase-Locked Loop (PLL), implemented in α-β coordinates (D Dβ-PLL), whereas the other one corresponds to the Enhanced PLL (E-PLL). The major contribution of this paper is to present a single-phase PLL oriented to power quality applications, with a very simple structure, capable to be synchronized with the fundamental component of an input signal (voltage or current), even considering substantial disturbances, such as, frequency deviations, phase shifts, harmonic components and amplitude variations. Simulation and experimental results, involving these two synchronizing circuits submitted to three different test cases, are provided in order to compare their transient and steady-state performance. Moreover, it is also presented a comparison involving the processing speed and memory requirements of these synchronizing circuits in the DSP TMS320F28335.

“…Active AC/DC converters ensure that the line current waveform complies with the applicable standards [1] and grid codes while regulating the DC voltage levels [2]. Searching for improvements in efficiency [3], power density and costs results in higher complexity control, involving multidisciplinary knowledge in design, development, testing and manufacturing stages [4].…”

Hardware-in-the-Loop and Digital Control Techniques Applied to Single-Phase PFC Converters

Power electronic converters for power factor correction (PFC) play a key role in single-phase electrical power systems, ensuring that the line current waveform complies with the applicable standards and grid codes while regulating the DC voltage. Its verification implies significant complexity and cost, since it requires long simulations to verify its behavior, for around hundreds of milliseconds. The development and test of the controller include nominal, abnormal and fault conditions in which the equipment could be damaged. Hardware-in-the-loop (HIL) is a cost-effective technique that allows the power converter to be replaced by a real-time simulation model, avoiding building prototypes in the early stages for the development and validation of the controller. However, the performance-vs-cost trade-off associated with HIL techniques depends on the mathematical models used for replicating the power converter, the load and the electrical grid, as well as the hardware platform chosen to build it, e.g., microprocessor or FPGA, and the required number of channels and I/O types to test the system. This work reviews state-of-the-art HIL techniques and digital control techniques for single-phase PFC converters.
