Aiming at the problem of low redundancy in structure cascaded H-bridge STATCOM. This paper studies and designs a STATCOM device based on STM32 distributed control. The article introduces basic topology realization principle control system. turn-on turn-off time MOSFET each is calculated by using law minimum harmonics, realize output fitted sine wave. A simulation model 12H bridge cascade built ...

Abstract This paper describes about solar energy is one of the sources that won’t terminated. Solar can be easily converted into electrical by using panels. panels are placed horizontally on ground, panel cannot absorb light perfectly. Therefore, require an automatic tracking system to increase efficiency In this study, a tracker has been designed dependent resistor (ldr) sensor based stm32 mic...

Abstract Monitoring the quality of photovoltaic power generation in remote mountain areas is difficult, so this paper proposes a real-time online monitoring system to solve problem by using AD7606 high-precision ADC chip and STM32 single-chip microcomputer. realizes acquisition conversion three-phase data. performs wavelet transformation on collected data obtain parameters. It stores parameters...
