基于16位單片機的逆變電源系統(tǒng)的設(shè)計

介紹了一種以8XC196MC 為內(nèi)核的逆變電源系統(tǒng)。其逆變控制系統(tǒng)實現(xiàn)了全數(shù)字操作。逆變部分的SPWM 控制脈沖波形完全由8XC196MC 單片機生成,使用IR2130 實現(xiàn)對功率管的驅(qū)動和保護,頻率電壓可由數(shù)碼管顯示,可用串口與上位機進行通訊.該系統(tǒng)硬件電路簡單，器件減少，結(jié)構(gòu)緊湊，性價比高。經(jīng)試驗表明：逆變電源輸出波形失真小，動態(tài)特性好，可靠性高。

Abstract: The inverter power system based on 8XC196MC is introduced. The controlling system is digital. SPWM control pulses are produced by 8XC196MC. Used IR2130 to drive and protect power transistor. Frequency and voltage are displayed. It can communicate with upper-computer. This system has the merits of simple hardware, compacted configuration, high output-stability, good dynamic characteristic and high dependability.
