摘要
介绍中频电源用单片机控制三桥臂的起动法,该法的优点:①可频繁起动,起动可基本无间隔;②可在全载全压下起动;③不受负载轻重的影响;④可适于更高频率的中频电源起动;⑤线路简单,成本低。
Introduces a new starting method of MF power source by use of monolithic processor to control the three inversion bridge arms. This method has following advantages: ①can be starting frequently and time interval is unnecessary basically; ②can be starting whether on the full load or on the full voltage; ③has no influence of load whether it is heavy or light during starting; ④can be suited for starting MF power source of relatively high frequency; ⑤has simple circuit and less cost.
