This paper is proposed to improve the efficiency of the series resonant inverter for industrial heating applications. Resonant inverters are those operate at high frequency with reduced losses preferable for induction heating. Resonating components and switching device which are placed in series to load forms series resonant inverter. Inverter which is characterized by full bridge made up of In...

This paper provides a direct dynamic modeling approach for envelope signals in resonant inverters driven by modulated inputs (AM or FM). Based on the sinusoidal approximation, this approach decomposes the modulated input into its fundamental component plus two dominant sidebands. The system response is then found by the summation of the responses to the three individual inputs. Following this c...

The averaged switch modeling technique unifies the modeling of PWM and resonant dc-dc converters, low-harmonic rectifiers, and inverters in a simple manner. This technique is briefly reviewed, and recent results in modeling current-programmed dc-dc converters, integrated single-phase low-harmonic rectifier-regulators, and single-switch three-phase lowharmonic rectifiers are described. A circuit...

In this paper, a review of PV inverters is reported based on converter characteristics as the number of energy processing stages, the presence of a transformer (high-frequency or 50Hz transformer), and the adopted configuration of the PV field. In particular, the considered solutions have been evaluated depending on efficiency, input current ripple and life-time of the capacitors coupling with ...

In this paper, a method for minimization of Total Harmonic Distortion (THD) is proposed in case of PWM inverter. Inverters are widely used in many applications such as in the UPS and ac motor drives resulting in harmonics production. A phase compensation Resonant Controller (RSC) is proposed for 1-phase pulse width modulation (PWM) inverter using MATLAB simulation. The simulation results are th...

Introduction: High-frequency DC-AC inverters as the LCC inverter shown in Fig. 1 are used in a variety of applications including electronic ballasts and induction heating. Input variations in both the bus voltage (amplitude modulation, AM) and the switching frequency (frequency modulation, FM) result in amplitude variations at the load. A common objective is to model the AC dynamics from input ...
