The resolver with large load in servo system is supplied with excitation signal by high accuracy sine wave oscillator with large driving capability.A new sinusoidal oscillator source suitable for the resolver was designed based on programmable oscillator AD2S99,the hardware circuit was illustrated,PSPICE simulation and real testing in servo system was implemented.Test results prove that the demand of the resolver with large load is satisfied and the foreign dedicated oscillator source chips,which are expensive and time-consuming to purchase,is substituted.The design has low cast,simple structure and high practicable.
