This article presents the development and design of a new type intelligent high potential therapeutic apparatus, by using Atmega1280 as its controller. The circuit transforms voltage from 220 V ac to 110 V ac and constitutes different circuits with relays. In order to get different treatment waveforms, inductance of various values is used in different circuits. The circuit generates appropriate treatment voltage with the transformer booster. Simultaneously, the corresponding control software was composed. Finally the hardware and software designs of the high potential therapeutic apparatus were completed. Result of the experiment showed that the high potential therapeutic apparatus worked steadily and the effect of treatment was satisfactory.
