- Abstract
One of an H bridge Cascaded multilevel inverters was studied and designed. In this paper, the basic topology of microcontroller based H-bridge cascade multilevel inverter and the realization principle of control system are introduced. The principle and control strategy of the inverter are studied and described. Calculated by multi-superposition method, H bridge in the power field effect of the turn-off time is supposed to achieve the sine wave output, ladder wave modulation, with the switching device work in the fundamental frequency, small loss, and high efficiency. Circuit control part of the STM32 series chip by STMicroelectronics as the master chip, the device can run normally in the two H bridge out of the cascade of the state, causing a substantial increase in the reliability of the device; In EMTP power system in the electromagnetic transient analysis and simulation software,we construct a simulation model of 12H-bridge cascade. The simulation results show that the device can operate stably in the 12H bridge cascade state and n-1, n-2 state, which indicates the correctness and reliability of the design. In addition, the experimental device of 12H-bridge cascade multilevel inverter is designed, which realizes the design function and feasibility of this thesis.
