-In this paper the integration between a voltage source inverter (VSI) and a switched capacitor converter (SCC) is proposed to generate a sinusoidal waveform with a double peak voltage value at the converter output terminal, without the use of a transformer or a dc-dc boost converter. The novel structure (VSI-SCC) is designed as a transformerless step-up inverter with linear gain. VSI and SCC models are individually characterized to integrate both structures in only one model. To validate the theoretical analysis a prototype was designed for a power of 1 kW, considering a dc input voltage of 200 V and an ac output voltage of 220 V (rms). In this prototype the VSI converter supplies 110 V (rms) to the SCC converter, and this converter step-up it to 220 V (rms). Furthermore, open and closed-loop control were also tested in the prototype reaching a maximum efficiency of 90%.

“…So heat is produced due to Joule's effect. At first to explain the steady state operation of a modified switched boost inverter, it is assumed that shoot through condition is intentionally created in the inverter for a duration of DT S in a switching cycle of T S [12][13][14]. During this shoot through state the switch S is turned on.…”

Abstract:A novel circuit topology of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment is presented in this paper for efficient induction heating. Recently, induction heating technique is becoming very popular for both domestic and industrial purposes because of its high energy efficiency and controllability. Generally in induction heating, a high frequency alternating magnetic field is required to induce the eddy currents in the work piece. High frequency resonant inverters are incorporated in induction heating equipment which produce a high frequency alternating magnetic field surrounding the coil. Previously this high frequency alternating magnetic field was produced by voltage source inverters. But VSIs have several demerits. So, in this paper, a new scheme of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment has been depicted which enhances the energy efficiency and controllability and the same is validated by PSIM.

ABSTRACT:The objective in this paper is to study the operating modes and analysis of the Switched Boost Inverter (SBI). The performance of the proposed SBI is similar to that of Z-Source Inverter (ZSI). In comparison to the ZSI, the present topology results in lower volume and lower cost since it reduces the number of passive component. This feature makes it more suitable for low power applications than ZSI.For the proper operation of the inverter, with special consideration to its operating principle (shoot-through i.e., conduction of two switches on the same leg of the inverter), a modified PWM control strategy is also described in detail. In addition, mathematical relations between various performance parameters under this modified PWM technique have been described in detail.Simulation is carried out using Matlab/Simulink software to verify the theoretical analysis made. This report also presents a laboratory prototype of the Switched boost inverter along with it results.KEYWORDS: Z-Source Inverter, Switched Boost Inverter, Modified PWM technique, Shoot-through, Non-Shootthrough. I.INTRODUCTIONZSI employs a unique impedance network to couple the converter circuit to the power source, thus providing unique characteristic features that cannot be found in the traditional Voltage source inverter and Current source inverter. The unique impedance network mentioned above, implements two capacitors and two inductors. Introduction of these passive components add weight and size to the whole inverter. In order to reduce size and weight, a new topology is considered which involves lesser passive components, meanwhile trying to attempt similarity in all the steady state performance. This new topology is called Switched Boost inverter, which is being studied and analysed in this report. II. LITERATURE SURVEYThe basic idea of SBI [2] is derived from ZSI [1]. By controlling the shoot-through duty cycle, the ZSI can be able to produce any AC output voltage from a given DC input voltage. This feature makes the ZSI suitable for number of applications such as renewable power systems (photovoltaic and fuel cells), adjustable speed drives, general purpose motor drives, electric vehicles, uninterruptible power supplies [3]-[8] etc.Conventional pulse-width modulation techniques can be modified strategically to affect the operation of ZSI continuously or discontinuously, while retaining all the harmonic performance features of the conventional modulation techniques [9]. The complete analytical performance of the ZSI using X-shaped LC impedance network is complicated. Hence a small signal model method is resorted in [10] to derive transfer function and asses the performance there upon. From literature survey it is evident that ZSI is a promising technology for both buck and boost operations. But ZSI has the drawback of employing more and bulky passive components. Therefore SBI topology has been proposed [2] to reduce the number of passive components, thus can be used in low power applications where size and weight matters.
