资料介绍

电源在人们社会生活当中随处可见,随着社会的发展,能源问题日趋严重,节能与能量回馈方面有着很大的研究意义。本文就直流转换成交流供给负载,再将负载上的交流转换成直流反馈到交流的输入端子,实现能量的反馈使用。装置主要分为2个部分,第一部分是DC-AC转换,该部分主要以STC12C5A60S2单片机为核心,通过自然数查表法控制硬件PWM模块生成SPWM脉冲信号,采用单极性调制方案驱动单相全桥逆变电路,输出经LC低通滤波器滤波,便可在负载上得到稳定的正弦波交流电。第二部分也以STC12C5A60S2单片机为核心调制PWM脉冲信号,经过MOS管驱动IIR2104芯片控制整个BOOST升压电路。单片机内部自带的10位ADC能通过电流电压检测实时反馈电流和电压数值,通过反馈值调整输出的PWM脉冲的占空比,形成电压闭环控制系统。按键能设置输出电流从0.1 A到2 A的限度。

Power supply is everywhere in the social h the development of society,energy problem is becoming more and more rgy conservation and energy feedback have great research this paper,DC is converted into AC supply load,and then AC on load is converted into DC and fed back to AC input terminal for realizing energy device is mainly divided into two first part is DC-AC core of this part is STC12C5A60S2 hardware PWM module is controlled by natural number table lookup method to generate SPWM pulse single-phase full-bridge inverter circuit is driven by unipolar modulation output is filtered by LC low-pass filter,and stable sinusoidal AC can be obtained on the second part also uses STC12C5A60S2 MCU as the core to modulate the PWM pulse whole BOOST circuit is controlled by IIR2104 chip driven by MOS 10-bit ADC in the MCU can detect the real-time feedback current and voltage values by current and voltage,and adjust the duty cycle of the output PWM pulse by the feedback value to form a closed-loop voltage control button can set the limit of output current from 0.1 A to 2 A.
