“…Table 1 shows comparisons between the conventional two-stage drive circuits in References [ 12 , 13 , 14 ] and the proposed single-stage one for the piezoelectric ceramic actuator. It can be seen that the proposed drive circuit has the characteristics of power-factor-correction and soft switching and requires fewer power switches than in References [ 12 , 13 , 14 ], so it can be a cost-effective alternative version for supplying a piezoelectric ceramic actuator.…”

This paper proposes a novel and cost-effective drive circuit for supplying a piezoelectric ceramic actuator, which combines a dual boost AC-DC converter with a coupled inductor and a half-bridge resonant DC-AC inverter into a single-stage architecture with power-factor-correction (PFC) and soft-switching characteristics. The coupled inductor of the dual boost AC-DC converter sub-circuit is designed to work in discontinuous conduction mode (DCM), so the PFC function can be realized in the proposed drive circuit. The resonant tank of the half-bridge resonant inverter sub-circuit is designed as an inductive load, so that the two power switches in the presented drive circuit can achieve zero-voltage switching (ZVS) characteristics. A 50W-rated prototype drive circuit providing a piezoelectric ceramic actuator has been successfully implemented in this paper. From the experimental results at 110V input utility-line voltage, the drive circuit has the characteristics of high power factor and low input current total-harmonic-distortion factor, and two power switches have ZVS characteristics. Therefore, satisfactory outcomes from measured results prove the function of the proposed drive circuit.

“…Two types of inverters are installed into high frequency induction heaters: voltage source and current source. In the past, series and parallel resonant inverter circuits were used in conjunction with half-bridge and full-bridge to reduce switching loss and increase circuit efficiency [7][8][9][10][11][12][13][14][15][16][17].…”

“…This makes it more difficult to operate both circuits since the system relies on many switches to function, resulting in significant switching losses. Jittakort proposed the variable frequency asymmetrical voltage cancellation control of a series resonant inverter [9][10][11]. The output power of the full-bridge inverter circuit is regulated via asymmetrical control frequency adjustment for series resonant loads.…”

This paper proposes the frequency control technique using a half-bridge resonance inverter for hot tensile testing in induction heating. The technique involves power regulation, high frequency pulse, frequency adjustment, and pulse generator controller based on the dsPIC33FJ16GS404 chip IC. Significantly, the inverter is controlled by two sections. Throughout the heating cycle, the first controller retains the inverter's operating frequency slightly above the resonant frequency, while the second keeps the phase angle of the current and voltage output in check to control the output power at a level suitable for changes in the tensile parameter workpieces. As a result, the inverter improves the efficiency of the prototype, which has 1.5 kW input power. Furthermore, it can heat three different sizes of steel workpieces for hot tensile testing, with diameters of approximately 3, 5, and 10 mm and lengths of approximately 50 and 70 mm, respectively.

SummarySingle‐phase high‐frequency resonant inverters (SPHFRIs) with high power density, fast dynamic response, and high energy conversion efficiency have been widely studied and used in academia and industry. With the development of the modularization concept, the operation of multiple inverter modules is desirable because it can remove the limitations of cost, heat dissipation, and component volume in single inverter operation. However, a critical challenge in multiple inverter systems is that the both the phase and magnitude of the output voltage of each inverter module must be controllable to eliminate circulating currents between inverter modules. Great efforts have been made to solve this problem from three aspects: topology, modulation, and control strategy. In this paper, modulation strategies and topologies of different inverters are presented and reviewed to provide guidance to researchers working in this field. Firstly, multiple inverter system based on the SPHFRI is described and its advantages and disadvantages are analyzed. An important issue in the study of multiple inverter systems is presented, that is, the suppression of circulating current. Secondly, the circulating currents in a multiple inverter system are analyzed and derived from two aspects: (1) magnitude and phase angle and (2) active and reactive currents. Thirdly, the inverters used in the multiple inverter system are introduced, and their operating principles, advantages, and disadvantages are reviewed. A key comparison of several inverters is presented for the benefit of the readers. Fourth, through PI closed‐loop simulation, the performance of different multiple inverter systems for suppressing the circulating current is compared in two situations: (1) with magnitude discrepancy only and (2) with both magnitude and phase discrepancy. Finally, the advantages and disadvantages of each inverter are summarized, and the state of the art and future trends are presented.
