“…The equivalent values of the IH system R eq and L eq are changed by the geometry, load materials, temperature and excitation frequency. These parameter variations make the output power control harder (Lucía et al, 2011). For this reason, a complete analysis for the equivalent parameters of the IH system is provided here.…”

ABSTRACT. This paper discusses about the fixed frequency pulse mask control based high frequency AC conversion circuit for industrial induction heating applications. Conventionally, for induction heating load, the output power control is achieved using the pulse with modulation based converters. The conventional converters do not guarantee the zero voltage switching condition required for the minimization of the switching losses. In this paper, pulse mask control scheme for the power control of induction heating load is proposed. This power control strategy allows the inverter to operate closer to the resonant frequency, to obtain zero voltage switching condition. The proposed high frequency AC power conversion circuit has lesser total harmonic distortion in the supply side. Modeling of the IH load, design of conversion circuit and principle of the control scheme and its implementation using low cost PIC controller are briefly discussed. Simulation results obtained using the Matlab environment are presented to illustrate the effectiveness of the pulse mask scheme. The obtained results indicate the reduction in losses, improvement in the output power and lesser harmonic distortion in the supply side by the proposed converter. The hardware results are in good agreement with the simulation results.

“…The half bridge SRI is operated at a switching frequency higher than the resonant frequency to achieve ZVS condition. To reduce the switching losses during turn-off, a lossless snubber network (C s ) is added (Lucía et al, 2011;Sarnago, Mediano, & Lucia, 2012). This operation mode ensures zero switching losses.…”

“…In the conventional fixed frequency modulation techniques, the ZVS condition is ensured only for limited range of duty cycle [12]. In the above mentioned methods, the output power control is difficult due to the variation of IH load parameters during the heating process [13][14][15]. With the variation in load parameters, non-ZVS operating condition results during the switching operation which causes more power losses [16,17].…”

-Power requirement to the induction heating system varies during the heating process. A closed loop control is required to have a smooth control over the power. In this work, a constant frequency pulse density modulation based power tracking control scheme for domestic induction heating system is developed using the Fuzzy Logic Controller. In the conventional power modulation schemes, the switching losses increase with the change in the load. The proposed pulse density modulation scheme maintains minimum switching losses for the entire load range. This scheme is implemented for the class-D series resonant inverter system. Fuzzy logic controller based power tracking control scheme is developed for domestic induction heating power supply for various power settings. The open loop and closed loop simulation studies are done using the MATLAB/Simulink simulation tool. The control logic is implemented in hardware using the PIC16F877A microcontroller. Fuzzy controller tracks the set power by changing the pulse density of the gate pulses applied to the inverter. The results obtained are used to know the effectiveness of the fuzzy logic controller to achieve the set power.

“…These controllers are usually described in VHDL or Verilog, but this is not the only possible solution. Literature shows examples of embedded µProcessors used for running C code [4]. The verification of the final regulator implies not only debugging its implementation, but also its interaction with the plant to be controlled.…”

Esta es la versión de autor de la comunicación de congreso publicada en: This is an author produced version of a paper published in: AbstractDebugging a digital controller for power converters can be a lengthy process due to the long time required in mixed-signal simulations. This paper focuses on the design of a power converter model for debugging digital controllers in closed loop. The testing may be performed by means of simulation or emulation. This paper shows the results of simulating and emulating the power converter using different data representations. Experiments will show that through a good selection of data and emulation, testing can be speeded up over 28, 000 times.
