基于STM32分布控制的级联H桥STATCOM设计
Design of Cascade H - bridge STATCOM Device Based on STM32 Distribution Control
For the current cascade H bridge STATCOM the structure of the redundancy is low; the cost of using IGBT higher; control system and trigger system power supply is more complex; system information transmission due to isolation needs, must use optical fiber communication, research and design A STATCOM 32-based distributed control of the cascaded H bridge STATCOM device. In this paper, the basic topology of the device and the realization principle of the control system are introduced. The turn-off time of the MOSFET in each H-bridge is calculated by the principle of low-order harmonic method, and the sine wave output is realized. Distributed control part of the STM32 series chip by STMicroelectronics as a control chip to control the trigger of each H bridge, information collection and information transmitted to the host as the DSP chip; EMTP power system in the electromagnetic transient analysis software to build a 12H Bridge cascade simulation model, the simulation results show the design of the correctness and reliability. In addition, the experimental device of 12H bridge cascade STATCOM is designed, which realizes the design function and verifies the feasibility of the article content.#$NLKeywords: Cascade H bridge, STM32, Distributed control, STATCOM;
