    • A control system for a transistor inverter comprising a circuit for detecting the load current or the output voltage from the inverter to produce a detection output; a circuit for outputting a control instruction for adjusting the load current; a leading angle forming circuit for combining the detection output with the control instruction to form a control signal corresponding to a leading angle at which the inverter output voltage is controlled with a leading phase relative to the load current; and a circuit receiving the control signal from the leading angle forming circuit and for forming a switching control signal, which is supplied to the switching devices in the inverter. The load current is not controlled directly by controlling the frequency of the inverter, but by changing the phase difference .gamma. between the load current and the inverter output voltage.
    • 一种用于晶体管反相器的控制系统,包括用于检测来自逆变器的负载电流或输出电压以产生检测输出的电路; 用于输出用于调整负载电流的控制指令的电路; 一个引导角形成电路,用于将检测输出与控制指令组合,以形成对应于相对于负载电流以超前相位控制逆变器输出电压的前导角的控制信号; 以及电路,从前导角形成电路接收控制信号,并形成提供给逆变器中的开关装置的开关控制信号。 负载电流不是通过控制变频器的频率直接控制,而是通过改变负载电流和逆变器输出电压之间的相位差γ来控制。
