基于物理农业的数控高压静电场电源设计

摘要

It has been widely used in physical agriculture that the germination rate and productivity of seeds are increased in high-voltage electrostatic field. For this reason, a kind of numerical-control electrostatic power supply is designed to produce 0-55 kV high-voltage electrostatic field, which can produces square wave controlled by a microcontroller to trigger SCR circuit. The experimental testing result shows that the high-voltage electrostatic field power supply can meet the needs of different seeds.%高压静电场可以激化种子内部活力,在物理农业中已得到广泛应用.为此,设计了一种数控高压静电场电源,该电源通过单片机编程进行零点检测和占空比调整,控制晶闸管触发,为高压产生电路提供0～200 V直流电压.同时,通过编程产生方波,作为激励脉冲信号,使高压电路产生0～55 kV的高压静电.经实验测试,该高压静电场电源能够满足不同种子的高压静电场需求.
