%X 本设计以STM32单片机为核心，采用PWM调制和SPWM调制技术分别对双向DC-DC和单相逆变电路进行控制，并通过PID算法对整体的硬件电路做了闭环调节，从而实现了可以输出固定频率和稳定电压的UPS电源系统。本系统主要包括变压器模块、双向DCDC模块、单相逆变模块、AD637交流采样模块。该UPS实现了可以输出固定频率和幅值的正弦交流电的功能，效率可以达到86%。<br />
This design is based on STM32 single-chip microcomputer, using PWM modulation and SPWM modulation technology to control the two-way DCDC and single-phase inverter circuit respectively, and the overall hardware circuit is closed loop adjusted by PID algorithm, so as to realize the output of fixed frequency and Stable voltage UPS power system. This system mainly includes transformer module, two-way DCDC module, single-phase inverter module, AD637 AC sampling module. The UPS realizes the function of outputting sinusoidal alternating current with a fixed frequency and amplitude.
