Design of Arbitrary Waveform Power Supply

Abstract: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.
