Abstract:
1. A micro-electric-field generator, comprising: a) a power supply unit; b) at least one micro-electric-field generating unit set comprising a step-down unit, a linear regulator unit, and a pulse generating and outputting unit; and c) a programmable logic control unit; d) an excess voltage protection unit; and e) an excess current protection unit; wherein: said micro-electric-field generating unit set is connected to an output end of said power supply unit and controlled by said programmable logic control unit; said step-down unit depresses a voltage of frequency power; said linear regulator unit regulates an output of said step-down unit; said pulse generating and outputting unit turns on/off an output of said linear regulator unit rapidly and periodically, forming a pulse output, and switches the voltage range of an output pulse of said linear regulator unit; said programmable logic control unit controls the characteristics of the output pulse from said pulse generating and outputting unit according to preset values and program procedures; said pulse generating and outputting unit connects to a network electrode group; said excess voltage protection unit is disposed at said output end of said linear regulator unit, and an input end of said excess voltage protection unit connects to said output end of said linear regulator unit; said excess current protection unit is disposed at an output end of said pulse generating and outputting unit, and an input end of said excess current protection unit connects to said output end of said pulse generating and outputting unit; an output of said excess voltage protection unit and an output of said excess current protection unit connect to an interrupt port of said programmable logic control unit; and when said excess voltage/current protection unit generates an excess-valued voltage/current signal, said programming logic control unit stops the pulse output of said pulse generating and outputting unit so as to protect a corresponding unit.
