Description

FIELD OF THE INVENTION

The present disclosure generally relates to electrical converters. More specifically, the present disclosure relates to a system for a cross-coupled dual topology configuration of switched-capacitor inverters.

BACKGROUND

The background description contains information that may be useful in understanding the present invention. It is not an admission that the information contained herein is prior art or relevant to the present invention, or that any publication expressly or implicitly referred to is prior art.

Power electronics have made significant advances in the last decade, particularly in switched-mode, non-inductive, and transformerless converters. These converters have several advantages including light weight, compact size and high power density due to the use of only switches and capacitors. Power electronic converters play an important role in energy conversion and are suitable for a wide range of applications.

Multilevel inverters are important for medium and high voltage applications because they minimize voltage stress when generating high voltage levels, reduce harmonic content, have compact filters, reduce EMI and improve efficiency. Conventional multilevel inverter topologies such as neutral-point clamped, flying capacitor, and cascade H-bridge have been widely researched and used in many applications.

Efforts have been made to develop complementarily switched capacitor amplifiers for pipeline analog-to-digital converters and other applications. For example, patent application no. EP2866346A1 refers to a switched capacitor amplifier comprising a switched capacitor network and a complementary push-pull amplifier. The switched-capacitor amplifier can dump a larger proportion of the charge provided by a power supply and flowing through the amplifier to a capacitive load at the output of the amplifier compared to switched-capacitor amplifiers that use single-ended class A amplifiers delivery. The switched-capacitor amplifier can be used in a converter stage of a pipelined analog-to-digital converter to improve power efficiency and/or bandwidth. It can also be used for other applications as a pipelined analog-to-digital converter.

Canadian patent application no. CA2643939A1 , refers to an electronic ballast for operating a lamp, which has a class E converter. When a lamp is connected, the output current of the class E converter has first and second half cycles of opposite polarity after a switching element of the class E converter is switched off. The electronic ballast has a measuring device for measuring the output current and a control device for setting a switch-on time of the switching element. In this case, the measuring device is designed in such a way that it determines a first output current value of the first half period and a second output current value of the second half period, with the control device for adjusting the switch-on time being supplied with a control variable which is based on the discrepancy between the two output current values.

However, the major problems with these topologies are the large number of semiconductor devices, the balancing of capacitor voltages, and the complex control techniques for larger numbers of multi-level outputs. Multilevel inverters have a wide range of renewable energy applications in modern power systems that require flexible and versatile converters for power conversion and voltage level stability. DC-DC converters are widely used in residential, commercial and industrial applications such as: in renewable energy conversion systems, electrical propulsion devices, etc.

Therefore, there is still a need to develop high-efficiency multi-level inverters. In this context, a system for a cross-coupled configuration of switched-capacitor converters with two topologies is presented.

The presented system uses the switched-capacitor (SCC) topology to develop a highly efficient multi-level inverter. The switched-capacitor topology is also used to design a DC-DC (DC-DC) configuration. The DC-DC converter configuration is also designed and validated for different voltage conversion ratios. Under Use Using the same topology, a DC-DC boost and buck configuration is developed without circuit reconfiguration. The goal of the presented system is to achieve high reliability performance for both the inverter and converter configuration by reducing harmonics and providing multiple voltage ratios.
