The performance of FFC-NMR power supplies is evaluated not only considering the technique requirements but also comparing efficiencies and power consumption. Since the characteristics of FFC-NMR power supplies depend on the power circuit topology and on the control solutions, the control design is a core aspect for the development of new FFC systems. A new hybrid solution is described that allows controlling the power of semiconductors by switches (ON/OFF mode) or as a linear device. The approach avoids over-design of the power supply and makes it possible to implement new low power solutions constituting a novel design by joining a continuous match between the ON/OFF mode and the linear control of the power semiconductor devices.

This paper proposes a novel virtual inertia control strategy for distributed power systems with high penetration of renewable energy sources. The strategy uses a quasi-Z-source power converter to emulate the inertia response of a synchronous generator by regulating the DC-link capacitor voltage in proportion to the grid frequency deviation. This paper analyzes the effect of inertia on the frequency regulation of a single-area power system and derives the parameter design method and limitations of the virtual inertia. The paper also introduces the working principle and modulation technique of the quasi-Z-source power converter and presents the virtual inertia control scheme based on a voltage-frequency controller. The paper verifies the feasibility and effectiveness of the proposed strategy through MATLAB/Simulink simulations and dSPACE semi-physical experiments. The results show that the proposed strategy can reduce the frequency deviation and rate of change of frequency (RoCoF) by 20% and 50%, respectively, under load disturbances. The paper demonstrates that the quasi-Z-source power converter can provide flexible and adjustable virtual inertia for distributed power systems without additional energy storage devices.

This article presents a wideband bias circuit with low parasitic inductance for high-power pulsed amplifiers. The proposed bias circuit works similarly to the traditional bias circuit in that it can ensure the transmission of microwaves from the power amplifier to the load while preventing the transmission of microwaves from the power amplifier to the power supply. By making the bias line shorter and the transmission line wider than the traditional bias circuit, the proposed bias circuit reduces its parasitic inductance. The reduction of parasitic parameters is critical for reducing the drain voltage overshoot of the high-power pulse power amplifier and ensuring its safety. The simulation results demonstrate that the proposed bias circuit has a lower parasitic inductance and a wider bandwidth. To validate the theory and simulation results, the traditional and the proposed bias circuits are fabricated using microstrip circuits. Both the simulation and experimental results indicate that the proposed bias circuit has a one-third lower parasitic inductance than the traditional bias circuit. Furthermore, the proposed bias circuit has a wider bandwidth. Full article

Multilevel inverters are able to provide loads with voltages of high power quality using several DC sources, capacitors, switches, and diodes in their structures. However, the usage of the higher number of semiconductor devices (switches and diodes) and capacitors causes an increase in losses and costs and decreases their efficiency. Thus, lowering the number of switches and capacitors is a challenging issue in designing a multilevel inverter. In this paper, an asymmetrical multilevel inverter is proposed that produces 19-level output voltages. The circuit is composed of nine switches, six diodes, two capacitors, and two isolated DC sources. In comparison with other topologies, the most important advantage of the introduced 19-level topology is the usage of a lower number of switches and capacitors, which leads to a decrease in the number of gate drivers and the total volume of the system. During the charging process, capacitors never connect to each other in series, i.e., they are self-balancing and do not require the extra circuits. The proposed topology offers a total harmonic distortion (THD) of 7.4% in the output voltage, which is less than 8%, complying with the IEEE standards. The performance of the topology is validated under various load conditioning through an experimental setup in the laboratory. Full article

By increasing the impedance of the microstrip of the combine port, a new Gysel power combiner/divider (PCD) with enhanced average power-handling capability (APHC) was proposed. This article shows the simulated results of the traditional Gysel PCD and the proposed Gysel PCD at the center frequency of 2.4 GHz and 10 GHz. For verification, one example of the proposed Gysel PCD operating at 2.4 GHz was designed, fabricated, and measured. One traditional Gysel PCD operating at 2.4 GHz was also fabricated to compare the APHC of the proposed Gysel PCD and the traditional Gysel PCD, by means of measuring the temperature variation of the microstrip line at the same power. The measurement result suggests the APHC of the proposed Gysel PCD is nearly twice that of the traditional Gysel PCD. Full article
