Multilevel power converters provide more than two levels of voltage to achieve smoother and less distorted ac to-dc, dc-to-ac, and dc-to-dc power conversion. This paper presents a generalized multilevel inverter (converter) topology with self voltage balancing. The generalized multilevel inverter topology provides a true multilevel structure that can balance each DC voltage level automatically ...

Classic high-frequency transformers enable for isolated DC/DC converters to achieve high input voltage gain by the turns ratio. Through the use of an isolation transformer made in planar technology with interleaved windings leakage inductance can be significantly reduced and voltage overshoots can be marginalized. By applying balancing transformer with integrated input inductor in the setup of ...

This paper proposes a high voltage ratio and low ripple interleaved boost DC-DC converter, which can be used to reduce the output voltage ripple. This converter transfers the low DC voltage of fuel cell to high DC voltage in DC link. The structure of the converter is parallel with two voltage-doublers boost converters by interleaving their output voltages to reduce the voltage ripple ratio. Bes...

In this paper, a single-phase multilevel inverter with battery balancing is proposedThe voltage source inverters produce a voltage with levels either 0 or ±V dc they are known as two level inverters.To obtain a quality output voltage or a current waveform with a minimum amount of ripple content, they require high switching frequency along with various pulse width modulation (PWM) strategies.As ...

In this paper, an improved maximum power point (MPP) tracking (MPPT) with better performance based on voltage-oriented control (VOC) is proposed to solve a fastchanging irradiation problem. In VOC, a cascaded control structure with an outer dc link voltage control loop and an inner current control loop is used. The currents are controlled in a synchronous orthogonal d, q frame using a decoupled...

This dissertation presents voltage stabilization techniques for flying capacitors used in soft-switching multilevel active power filters. The proposed active filter has proved to be a solution for power system harmonics produced by static high power converters. However, voltage unbalance of the clamping capacitors in the active filter in practical applications was observed due to its unequal pa...

Space Vector Modulation (SVM) Technique has become the most popular and important PWM technique for three phase Voltage Source Inverters. Z-Source Inverters have the ability to boost the dc link voltage, thus increasing the output ac voltage beyond the values reached by conventional inverters. The enhanced ratio from ac output voltage to dc link voltage is possible due to an impedance network c...
