【摘要】 介绍了农用电机中开关电源的设计原理,以及电路结构特点。通过电路中的脉冲宽度调制方式得到固定周期的控制信号,同时结合电路中的滤波电路,从而使工作组中的农用电机得到平滑的工作电流,进而提高了农用电网中电能的质量。为此,对电源的内部结构给出了新型设计,它不但使得电路工作可靠,而且减少了电源本身的功耗。更多还原

【Abstract】 This paper discussed the theory of switch power in agriculture motor and the circuit characteristic. The switch power get fixed signal by PWM control mode and use the strain circuit of wave to supply the smooth current to the workgroup agriculture motor, and to improve the quality of power net. This paper introduces a new power structure circuit. The new structure circuit design not only makes the circuit work safely, but also reduces the consumption itself.更多还原
