The invention discloses a DBD type ozone generator internal voltage separation device and separation method. The voltage separation device mainly comprises a current and voltage detection circuit, a signal operation circuit and a digital signal processing unit. The signal operation circuit is mainly composed of a phase-locked loop, a frequency doubling unit, a multiplier, an integrator and a summator. Various signals required by the separation device can be formed by measuring alternating voltage applied to the ozone generator, current flowing through the ozone generator and current flowing through the high-frequency inverter power supply, and ozone generator air gap voltage and ozone generator blocking medium voltage can be separated from the measurable alternating voltage of the ozone generator. The problem that the internal voltage of the ozone generator cannot be effectively separated at the present stage is solved. 本发明公开了一种DBD型臭氧发生器内部电压分离装置及分离方法，该电压分离装置主要包括电流电压检测电路、信号运算电路和数字信号处理单元。其中，信号运算电路主要由锁相环、二倍频单元、乘
