摘　　要：用计算机来控制高性能(功率,电压范围宽,低纹波因数和低响应时间)电源通常是昂贵的。本文提出了一种简单而有效的直流控制系统,它是基于商业的V/F逆变器相结合的三相桥式整流器和LC滤波器。由于逆变器的V/F变频范围广泛,当需要宽范围的电压时,无定形或铁磁芯的线圈是不行的,空芯线圈成为实现滤波和提高电力系统效率的一个很好的解决方案。该方法设计的LC滤波器是基于滤波器被连接的负载设置和系统的期望极点选择的全动态模型。通过建模与仿真来证明即使在低电压输出要求下,该拓扑结构仍可以获得良好的响应时间(设定时间小于100毫秒)和良好的纹波系数(小于1%),并不出现超调现象。Using a computer to control a high-performance (power, wide voltage range, low ripple factor and low response time) power is usually expensive. This paper presents a simple and efficient DC control system, which is based on a commercial V/F in-verter combines three-phase bridge rectifier and LC filter. Since the inverter V/ F frequency range wide, when you need a wide range of voltage, amorphous or ferrite core coil is not enough, the air-core coils can be the filtering and improving the efficiency of the power system a good solution. The design method LC filter is full dynamic model of the desired filter is connected to the load setting and the system poles choice. Through modeling and simulation to prove even at a low voltage output requirements, this topol-ogy can still get a good response time (setting time less than 100 ms) and good ripple factor (less than 1%), does not overshoot phe-nomenon.
