摘　　要：介绍一种幅值和频率都连续可调的任意波形电源,针对电磁阀性能检测而设计,具有较好的稳定性、精确性、安全性和快速启动性,可以瞬间输出10A电流。以单片机为控制系统,控制DDS模块产生1Hz～10KHz的波形信号,控制放大模块对其进行幅值和功率放大,得到0V～40V的波形信号,作为电源的最终输出。In this paper,a arbitrary waveform power supply is introduced,which frequency and voltage is continuously controllable,and which is designed to detect the performance of a solenoid.The power supply is stability,accuracy,security,it can fast startup and output a current about 10 AMP immediately.A singlechip is used as control system to control both the DDS module and the Magnifing module.The DDS module generate a signal with the frequency from 1Hz to 10KHz,and the Magnifing module magnify the amplitude and power of the signal,then a signal with amplitude from 0V to 40V is generated,finally the signal is used as the output of the power supply.
