摘　　要：基于高效稳定DC-DC开关电源集成芯片LT8705,对逆变电源进行了整体设计。其四开关Buck-Boost电路较好地克服了传统Buck-Boost电路损耗大和共模噪音大的缺点。为使该电源达到更好的工作性能,对Buck-Boost升降压区电路、电感电流检测电路等外围电路进行设计。同时,针对正弦波逆变电源系统,提出了一种可以实现高精度电压调节的比例积分微分(PID)控制方案。结合该逆变电源实际,利用Matlab进行仿真验证并使用硬件实现。对逆变电源进行实验测试,结果表明逆变电源具有宽范围、高效率、低功耗的特点。Based on the high efficiency and stable DC-DC switching power supply integrated chip LT8705,the thesis designs the inverter power supply as a whole.The four-switch BUCK-BOOST circuit overcomes the disadvantage of high loss and common mode noise of traditional BUCK-BOOST circuit.In order to achieve better performance of the power supply,the peripheral circuits such as BUCK-BOOST voltage region circuit and inductive current detection circuit are designed and realized.At the same time,for the sinusoidal inverter power supply system,a PID control scheme which can realize high precision voltage regulation is proposed.Combined with the actual inverter power supply,we use MATLAB to verify the simulation and get the hardware implementation.Finally,the inverter power supply is tested experimentally.Results show that the inverter power supply has the characteristics of wide range,high efficiency and low power consumption.
