    Details of SPWM inverter power module based on STM32 single-chip microcomputer

     

    Function Description This module can convert a DC input voltage of 4.5V to 35V to ± 4.5V- ± 35V AC voltage. The module uses STM32F030F4P6 microcomputer to generate SPWM wave driver L298 modules, and the L298 module integrates an H-bridge circuit, and integrates driving H bridge. The circuit, greatly reduces the difficulty of the SPWM drive H bridge, only needs to add a smooth sinusoidal voltage waveform to the L298 output, and can be loaded, the output current can reach 1.5A; convenient for you to learn the single-chip generation SPWM principle; can also control the output amplitude and frequency by serial port command; The STM32 single-chip (STM32F030F4P6) generates two SPWM waves, onboard serial port download, convenient for users to program; The post-stage LC filter output, the waveform is high; Output 50 Hz sinusoidal AC voltage; Enter the DC voltage range (4.5 ~ 35V); Output AC Effective Voltage Range (3.1 ~ 24V); Output maximum current 1.5A; Wide voltage input without additional driving IC power supply Information description Annex Content provides a schematic PDF version. The program is written in C language, compiled by Keil software, and the file is an engineering source code. , Read full text, original title: STM32 single-chip SPWM inverter power module production information Article Source: [Micro Signal: WW_CGQJS, WeChat Public Number: Sensor Technology] Welcome to add attention!
