“…Hence, the output current amplitudes are (12) If T << τ the amplitude of the output current (9) is proportional to T on /T, thus, the output power is given by (13) If T >> τ output voltage and current becomes discontinuous waveforms and the output power can be written as (14) If output power is larger than 25 %, the parameters V max and P max , defined for T on =T, and V min , for T on =0 are given by (15) Therefore the output power value must be inside of the limits calculated in (13) and (14) ( 16) In the other case, when output power is less than 25 % V max and V min are given by (17) and the inverter output power is in the range of (18) Fig. 8 shows the graphic representation of equations (16), in the right traces, and (18) in the left traces. Dashed lines represent the limits corresponding to low values of τ and solid lines are valid when τ tends to infinity.…”

This paper presents a 100 kW, 100 kHz IGBT series resonant inverter for induction heating applications that uses an improved power control scheme based on the standard pulse density modulation (PDM). This standard power control is a good solution for the design of high frequency inverters because the output power factor is near to unity in a wide range of output power, resulting in a great reduction of switching losses and electromagnetic noise. However, the output current can be in discontinuous mode especially for resonant loads of low quality factor or for low output power or low load operation. This output current fluctuation produces a high output current ripple that can lead to an increase of power losses and loss of accuracy of the response of the frequency tracking control. The proposed control strategy, called enhanced pulse density modulation (EPDM), provides twice less output current ripple, thus resulting in an improved inverter behaviour in terms of frequency tracking accuracy and energy efficiency. Experimental tests have been made in order to compare the EPDM strategy with standard power control schemes.

“…SiC Schottky diodes are available from several manufacturers, including Cree, IXYS, Infineon, and STMicroelectronics; SiC controllable switching devices in a variety of voltage and current levels are commercialized, such as JFETs from SemiSouth, metal-oxide-semiconductor field-effect transistors from Cree, and BJTs from TranSiC [92], [93]. GeneSiC and Cree have also developed a series of hybrid Si-IGBT/SiC-diode copack units and modules, up to 1,200 V/11 kW [94], where the latest generation of low-loss IGBTs is paired with SiC diodes instead of traditional Si diode. At the state of the art of semiconductor manufacturing, PV market demands, and ZS/qZS-CMI-based PV systems [57]- [63], ZS/qZS-CMIs cooperating with SiC devices can be considered as a future trend in highpower PV conversion technology.…”

T he current and emerging investigations on Z-source/quasi-Zsource inverters (ZSIs/qZSIs) are presented. The ZSI/qZSI fulfills buck/boost capability in single-stage topology and overcomes the limits of traditional voltage source inverters (VSIs). Hence, high reliablity, high efficiency, and low cost can be achieved. The recently derived impedance networks with improved voltage gain are discussed. The classic and newly proposed modulations and feedback controls for ZSIs/qZSIs are compared. Finally, the emerging applications and trends of ZSIs/qZSIs to photovoltaic (PV) power generation are discussed. This study offers a comprehensive and systematic reference for the future development of the high-performance ZSI/qZSI.The ZSI [1] and qZSI [2] were proposed in 2003 and 2008, respectively, to overcome the barriers of traditional two-level VSIs and current source inverters (CSIs). Traditional VSIs have to perform dead time between the upper and lower switches in one bridge leg to avoid short circuit, which introduces ac output waveform distortions. On the other hand, an extra dc-dc boost converter is usually required

Resonant power conversion is a key enabling technology of dc-dc conversion, inverters and contactless energy transfer systems. This paper presents an analytical model of the series resonant half-bridge topology aimed at improving the design, control and efficiency of resonant power converters. The main contribution is a closed-form expression of the main converter waveforms as well as output power and efficiency. This model enables a fast design-space exploration, as well as the implementation of advanced control techniques using adaptive control or real time emulation, significantly improving the converter operation. The analytical expressions presented have been applied and verified through a half-bridge series resonant inverter applied to induction heating applications, proving the accuracy and effectiveness of the proposed model. 0885-8993 (c)
