“…NDUCTION heating (IH) generators are resonant inverters in which the resonant tank is formed by the heating coil and a series capacitor, in series resonant inverters (SRI) [1]- [3], or a parallel capacitor, in parallel resonant inverters (PRI) [4] [5]. They are used to heat metals to be welded, melted or hardened [6] [7].…”

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.

“…From the circuit diagram shown in Figure 4a, it can be seen that there are two paths for load current in each half cycle. In the positive half cycle, the two paths for the load current are S 1a , D 1 , load, S 4a , D 7 and S 2b , D 3 , load, S 3b , D 5 , respectively. In the negative half cycle, the two paths for the load current are S 4b , D 8 , load, S 1b , D 2 and S 3a , D 6 , load, S 2a , D 4 , respectively.…”

Prevalent converters for induction heating (IH) applications employ two-stage conversion for generating high-frequency magnetic field, namely, AC to DC and then DC to high-frequency AC (HFAC). This research embarks upon a direct conversion of utility AC to high frequency AC with the design of a single-phase matrix converter (SPMC) as a resonant converter using a modified switching technique for IH application. The efficacy of the proposed approach is validated through different attributes such as unity power factor, sinusoidal input current and low total harmonic distortion (THD). The developed prototype-embedded system has high pragmatic deployment potential owing to its cost effectiveness using Arduino mega 2560 and high voltage/current as well as low switching time IXRH40N120 insulated-gate bipolar transistor (IGBT). Different results of the prototype-embedded system for IH application have been verified using Matlab Simulink environment to corroborate its efficacy.

“…The proposed technique is composed of a single PWM switching cell connected to both of the outputs of the PV and wind energy sources in parallel. Definition of the PWM switching cell is a circuit unit which consists of a pair (or more) of switching elements through which the whole power conditioning system is controlled by the complementary operation [21][22]. In proposed scheme, the digital controller senses the voltage and current of the PV and wind sources, and then based on P&O algorithm, the digital controller modulates the duty-cycle and switching frequency of the gate signal for the main switch in the switching cell in order to locate the output voltage (V C ) of the PV source and output current (I wind ) of the wind generator at each of the MPPs simultaneously.…”

-This paper proposes the modeling and control strategy to track the MPPs of hybrid PV and Wind power systems, using a new dual input boost converter. The dual input power conditioning system with an independent MPPT control scheme is introduced with minimum number of circuit elements in order to reduce the switching loss, size and cost of the system. Since the operating conditions for the PV and Wind power systems are very distinct from each other, an efficient and superior control system is required to track the MPPs of both renewable sources with the use of a simply-structured single-ended single-inductor converter. The design of Power-Conditioning System (PCS) and detail control strategy are presented in this paper. To provide independent tracking of MPPs, a variable duty-cycle control strategy is employed for the wind system and a variable frequency strategy is employed for the PV system. Finally, the proposed dual-input converter for hybrid power conditioning system is implemented and the hardware test results are presented. From the hardware experiment, it is concluded that the proposed system successfully tracks the MPPs of both of the renewable power systems independently.
