A Single DC Source Generalized Switched Capacitors Multilevel Inverter with Minimal Component Count

Abstract

This paper presents a new single-source switched capacitor- (SC-) based multilevel inverter (MLI) design with a boosting potential of three times the supply voltage. To produce a waveform with seven output voltage levels, the suggested switching capacitor inverter consists of eight switches, single diode, and two capacitors. Because capacitors are inherently balanced, there is no need for a balancing circuit or sensor. The structure can be expanded using the provided generalized equations. In addition, the technique for switching control and loss analyses is explored. A fair comparison with the most recent SCMLI topologies has been conducted to demonstrate the merits of the proposed work. Furthermore, the proposed topology is evaluated using the MATLAB/SIMULINK tool, and experiments under both transient and steady-state situations are performed to demonstrate its feasibility. At dynamic-loaded situations, the performance of the proposed SCMLI with dynamic modulation index and switching frequency is tested.

A single‐source switched‐capacitor‐based 25‐level sextuple boost inverter with a low switch count

“…The delay in the conduction function of the switches in turning on and turning off, which is related to the nonideality of the switches, leads to energy loss (E sw ). The wasted energy during the turning on and off time intervals can be calculated through Equation (22). Therefore, the switching loss during the switching process is according to (23).…”

“…This structure is less stressed because only two switches withstand the maximum output voltage. In Jena et al, 22 a seven‐level waveform with a boost factor of three is generated by an input power supply, two capacitors, eight switches, and a diode. In reference to Jena et al, 23 a seven‐level topology with less equipment stress is suggested.…”

“…However, the mechanical relay requires a separate control mechanism. Two partially-coupled coils with two HB inverter is developed in [20]. The self and mutual coupling inductance were measured using the finite element calculus method.…”
