    • An arrangement of interconnected timers is provided for operation with a microprocessor programmed to determine time delay counts that are fed out to these timers such that the timers can take care of the actual task of firing GTO inverter switches or not firing GTO inverter switches coupled with an AC traction motor for a vehicle. It is necessary to have correct transitions between the minus GTO switch and the plus GTO switch being ON for providing the desired motor voltage conditions with minimum electromagnetic interference in relation to the power supply. In addition the use of timer queues in complicated synthesis modes like the PWM and the quasi six-step operates to give the microprocessor adequate operating time for reasonable control signal time duration calculations. The timers are synchronized in hardware by a single crystal frequency, and they are synchronized in software such that the three phase independent waveforms stay 120.degree. apart.
    • 提供了互连定时器的布置,用于与被编程用于确定馈送到这些定时器的时间延迟计数的微处理器进行操作,使得定时器可以处理点火GTO逆变器开关的实际任务,或者不触发GTO逆变器开关 用于车辆的交流牵引电动机。 必须在负GTO开关和正GTO开关之间进行正确的转换,以提供与电源相关的最小电磁干扰的所需电机电压条件。 此外,在复杂的合成模式(如PWM和准六步)中使用定时器队列可以为微处理器提供合理的控制信号持续时间计算的足够的工作时间。 定时器通过单晶体频率在硬件上同步,并且它们在软件中同步,使得三相独立波形间隔120°。
