【摘要】 介绍了一款低成本单进三出逆变器的设计经验,硬件成本控制在60元人民币以内时,可驱动1 kW以下的三相笼式异步电机。总结了经过近百多次的修改后得到的较为成熟的电路的设计要点,包括微处理器,功率器件,半桥驱动,过流保护,控制方法,试验结果等方面的内容。用该电路实现的变频调速可以因低成本而大大扩展其应用范围,稍加修改后可用于直流无刷电机的驱动。更多还原

【Abstract】 The article recommend a way to design inverter in low cost.AC motor and BLDC under 1kw can be drived.The electrocircuit has been modified many times to make it more efficient.Questions of circuitry design were discussed such as microprocessor,half bridge driver,MOSFET/IGBT,safeguard,SPWN,outcome of test,etc.更多还原
