This design adopts STM32F407 single-chip microcomputer as the main control chip, adopts full-bridge inverter two-stage conversion, and obtains an ideal sinusoidal power supply, and has various protection functions. The external keyboard and liquid crystal display of the system have good human-computer interaction. II. SYSTEM DESIGN
This is a project intended for the matter of industrial eletronics. The goal is to develop a single phase inverter using SPWM modulation. It''s using the pins PA7 and PA8 to generate the PWM. PA7 is the normal PWM and PA8 is opposite to PA7. This two pins go in the H bridge. The code also has a feature to change the signal frequency trough serial.
The detection method used in this implementation for a single-phase inverter is based on a synchronous reference frame PLL. While in three-phase inverters the use of DQ based PLL is quite common, for single-phase inverters, the necessity of a virtual bi-phase system arises.
A prototype has been realized and a fully digital control algorithm, including power management for grid-connected operation and an MPPT (maximum power point tracking) algorithm, has been implemented on a dedicated control board, equipped with a latest generation 32-bit (STM32F103xx) microprocessor.
