“…Due to the symmetry of the threephase input system, the role of the input phases can be swapped in the input sectors to form the six-pulse rectified voltage, as shown in Figure 2b. If there are enough blocks in each sector, it can be assumed that in one block, the instantaneous line-to-line voltage is practically constant 38 . Let δ PDM (t) be the pulse density of the switches used to create the line-to-line voltage in that block; then, the average line-to-line voltage in the block (VPDM) will be proportional to this pulse density, as in (8):…”

With flexible voltage adjustment without an intermediate DC/DC converter, short-circuit protection, self-starting, high reliability, and three-phase current source rectifiers (CSRs) are being widely used in high-power medium-voltage applications and low-power low-voltage applications. Modulation methods significantly affect the performance of CSRs and can be categorized into offline modulation methods, such as selective harmonic elimination/compensation pulse width modulation (SHE/SHC-PWM), and online modulation methods, such as space vector pulse width modulation (SV-PWM) and carrier-based pulse width modulation (CB-PWM). The SHE/SHC-PWM is popular in high-power medium-voltage applications that do not require a fast dynamic response and have a low switching frequency. Online modulations considerably improve the dynamic response and performance of the CSR; however, high computational power, such as digital signal processors (DSPs), is required at higher switching frequencies, leading to greater system complexity and cost. In this paper, an offline method based on variable pulse density modulation (VPDM) of power switches to synthesize sinusoidal input currents and control power transfer with pulse width modulation (PWM) is proposed. The proposed modulation is applicable to the three-switch buck-type VIENNA rectifier, showing the capability of improving the input current total harmonic distortion (THD) with respect to the SHE-PWM and is comparable to online modulations at a sufficiently high switching frequency. The simulation and experimental results basically prove the feasibility of the proposed modulation.

“…Other approaches include multi-inductor [29][30][31][32][33], high-efficiency [34], or selectable induction heating target systems [35,36]. Besides, several direct ac-ac converters have been proposed for IH applications [37][38][39][40], reducing the number of components and increasing the efficiency and performance. However, current design trends are moving towards cost-effective implementations that can achieve the high performance demanded by the user, forcing the designer to develop new optimized power converter topologies.…”

Induction heating technology provides efficient and reliable heating processes that outperforms other classical heating methods based on fossil fuels or resistive heating. Among its many industrial, domestic and biomedical applications, domestic induction heating appliances are a popular choice due to these advantages. This technology requires high-performance and cost-effective inverters that takes the most of the power devices and the converter topology. Depending upon the desired performance and output power range, different power converters are employed. However, currently, most platforms rely on the well-known series resonant half-bridge topology. Single-switch topologies offer a cost-effective implementation but are limited to the low-cost low-performance markets due to their limitations in terms of output power and power control.In this context, this paper proposes a high-performance dual-output quasi-resonant inverter for modern induction heating appliances. Unlike state-of-the-art proposals, this converter achieves full output power operating range up to 3.6 kW. Consequently, it provides a high-performance costeffective alternative to current implementations. The proposed converter is analyzed in this paper and experimentally verified using a dual-output 3.6-kW induction heating appliance prototype.

This paper presents an improved topology for three-phase to single-phase matrix converter (3-1 MC), and discusses the power decoupling method, closed-loop control strategy, etc. These studies make the single-output MC have good features, such as sinusoidal input current, low total harmonic distortion (THD), compensating the shortcomings of traditional 3-1 MC caused by the output power pulsation. According to the improved scheme, a novel closed-loop control strategy based on virtual dc voltage feedback is proposed. The strategy completes the closed-loop control of 3-1 MC by taking the virtual dc voltage as outer-loop controlled variable and the input current as inner-loop controlled variable. Consequently, the power factor correction (PFC) of 3-1 MC is achieved, and the control stability is improved. Finally, a series of stimulation and experiments for a prototype with 115V/400Hz output are conducted, the results show that the power decoupling method and control strategy are practically correct and feasible.
