The invention discloses an auxiliary control circuit for a microfocus X-ray source. The auxiliary control circuit comprises a cathode driving circuit, a grid driving circuit and a filament driving circuit, each of the cathode driving circuit, the grid driving circuit and the filament driving circuit comprises a driving control module, a rectification output module and a loop adjusting module which are connected in sequence; the driving control module is used for acquiring a driving voltage through a half-bridge push-pull boost mode based on the gain voltage and transmitting the driving voltage to the rectification output module through a transformer; the rectification output module is used for carrying out rectification processing on the driving voltage so as to output working voltage; and the loop adjusting module is used for comparing the working voltage with the reference voltage based on a loop adjuster so as to obtain a gain voltage, and feeding back the gain voltage to the driving control module.
