A simple innovative nine-level, four-time boosting switched capacitor multilevel inverter topology is presented here with self-balancing capacitor. The suggested topology is considered with five pairs of switches, three capacitors, one diode, and single DC supply. The proposed dc-ac inverter has less number of switches and good quadruple boosting factor along with lesser stress on the switches. The suggested topology is discussed and analyzed for total standing voltage (TSV) and cost function (CF). It is also simulated in MATLAB environment to compare the various parameters in terms of number of switches, diode, and available capacitor and other vitals, also proving to be superior to many equivalent topologies. Level shift pulse width modulation (LS-PWM) scheme is used to produce the switching signal to the switches involved in the topology. Moreover, the topology is a good option to have additional advantage when it is implemented with off-grid applications. Comprehensive study puts the proposed inverter in a special category as its various advantages are discussed later in this chapter. Simulation results show that four-time boosting, TSV(pu) of 4.75 and CF of 3.19 are obtained, which proves the usefulness of the afore-stated topology and opens the opportunity for some advancement in the field of power electronics and drives.

摘要

A simple innovative nine-level, four-time boosting switched capacitor multilevel inverter topology is presented here with self-balancing capacitor. The suggested topology is considered with five pairs of switches, three capacitors, one diode, and single DC supply. The proposed dc-ac inverter has less number of switches and good quadruple boosting factor along with lesser stress on the switches. The suggested topology is discussed and analyzed for total standing voltage (TSV) and cost function (CF). It is also simulated in MATLAB environment to compare the various parameters in terms of number of switches, diode, and available capacitor and other vitals, also proving to be superior to many equivalent topologies. Level shift pulse width modulation (LS-PWM) scheme is used to produce the switching signal to the switches involved in the topology. Moreover, the topology is a good option to have additional advantage when it is implemented with off-grid applications. Comprehensive study puts the proposed inverter in a special category as its various advantages are discussed later in this chapter. Simulation results show that four-time boosting, TSV(pu) of 4.75 and CF of 3.19 are obtained, which proves the usefulness of the afore-stated topology and opens the opportunity for some advancement in the field of power electronics and drives.
