The invention provides an AC high-voltage module, a high-precision high-voltage AC/DC power supply device based on digital modulation and a broadband-adjustable high-voltage AC/DC power supply method. The AC high-voltage module converts direct-current voltage into alternating-current voltage through a first full-bridge inverter circuit, then the voltage is converted into a high-voltage alternating-current voltage under the action of a transformer, and adjustable broadband output is realized by adopting a PWM + SPWM control circuit; The high-precision high-voltage AC/DC power supply device based on digital modulation comprises an AC high-voltage module and a DC high-voltage module which are parallel, and high-voltage AC/DC output with an adjustable broadband is achieved. Through high-precision sampling, the high-voltage AC/DC power supply device with high precision and high stability is realized. 本发明提供了一种交流高压模块、一种基于数字调制的高精度高压交直流电源装置以及一种实现宽带可调的高压交直流供电方法，其中交流高压模块通过第一全桥逆变电路将直流电压转变为交流电压，后在变压器的作用下转换为高压交流电压，采用PWM+SP
