说明：  单片机直流无刷电机驱动单片机直流无刷电机驱动(moto driver)

说明：  逆变器将直流电转化为交流电，若直流电压较低，则通过交流变压器升压，即得到标准交流电压和频率。对大容量的逆变器，由于直流母线电压较高，交流输出一般不需要变压器升压即能达到220V，在中、小容量的逆变器中，由于直流电压较低，如12V、24V，就必须设计升压电路。(The inverter converts DC into AC. if the DC voltage is low, the standard AC voltage and frequency can be obtained by boosting the voltage through the AC transformer. For large capacity inverters, because of the high DC bus voltage, the AC output can reach 220V without transformer boosting. In medium and small capacity inverters, because of the low DC voltage, such as 12V and 24V, the boost circuit must be designed.)
