This paper presents a nonisolated, high boost ratio hy-brid transformer dc–dc converter with applications for low-voltage renewable energy sources. The proposed converter utilizes a hy-brid transformer to transfer the inductive and capacitive energy simultaneously, achieving a high boost ratio with a smaller sized magnetic component. As a result of incorporating the resonant operation mode into...

This paper proposes a flexible D-STATCOM (Distribution Static Compensator) and its new controller system, that be able to mitigate all types of faults (LG, DLG, LL, LLL and LLLG), and improve the distribution system performance. This paper validates the performance of D-STATCOM system to mitigate the power quality problems such as voltage flickers, voltage sags/swells harmonics and improve the ...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

In this study, an integrate modeling and controlling of DC-DC boost converter topology is proposed. The traditional DC-DC boost converter topology has the major drawback such as the input power supply is an unregulated rectified voltage and the load on converters is affecting the effectiveness of the converter. The proposed boost converter topology is differed from the traditional boost convert...

This paper presents a novel sparse matrix converter configuration that needs no bulky energy storage capacitors or inductors, and employs only unidirectional power semiconductor switches. The source side bridge is switched at the line frequency and therefore, this allows the use of the low speed high power rating switches. This feature and the use of diode-clamped multilevel topology at the out...

The design and characterization process of a package-embedded spiral inductor is investigated in this paper via comprehensive electromagnetic simulations. A realistic, multi-layer flip-chip package is considered and modeled in a commercial, full wave electromagnetic simulator. At constant package area, parasitic resistance of a given inductance is minimized. The applicability of the proposed pa...

In this paper a complete multi input-multi output state-space average model for the KY buck-boost converter is presented. The introduced model includes the most of the regulator’s parameters and uncertainties. In modeling, the load current is assumed to be unknown, and it is assumed that the inductor, capacitor, diode and regulator active switches are non ideal and have a resistance in conducti...

Here an improved three-level integrated ac–dc converter is presented. This converter improving or boosting power factor correction. And also this converter topology is advanced than previous ac-dc converters mainly the converter is operating with two independent controllers. An input controller is used to power factor correction and it regulates the dc bus, and the output controller is used to ...

This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...
