关于下阶段的计划和需求
昨天下午陈冰老师跟我们集中讲了三方面的知识: (1) 电机的原理与控制。 讲了电机的控制原理,通过桥电路控制通断,形成pwm波来控制电机。最开始是MCU控制控制器,在控制器里再加个MCU 通过外部MCU与控制器内的MCU通信来控制是更“轻松”的方法,把“脏活累活”都交给控制器自己去干。...

开关电源-BUCK
DCDC 称为直流直流变换,将直流电进行斩波,形成脉动的直流电压,最后经过储能,滤波电路留平滑输出,使得输出为直流电。在这期间运用PWM或PFM调制方法。(PWM:pulse width modulation,指的是一个周期内,改变有效脉冲的宽度,而频率不变),(PFM:pulse frequ...
