In order to meet the demand of the signal test device of phase-sensitive, by modeling and simulating on the transient stability and load change resistance, the control stability of variable frequency power is increased with parameter configuration, increased phase margin and amplitude margin. Besides, using ARM embedded kernel control chip the dual variable frequency power is established with the current loop model and the voltage loop model to have a simulation test, furthermore, a PI control strategy was applied to control the voltage fluctuation and improve the dynamic performance as well as stability of the device.
