EWB做的多功能数字钟 由振荡器输出稳定的高频脉冲信号作为时间基准，经分频器输出标准的秒脉冲，秒计数器满60向分计数器进位，分计数器满60向小时计数器进位，小时计数器按“12翻1”规律计数，计数器经译码器送到显示器；计数出现误差可用校时电路进行校时、校分、校秒， 可发挥部分：使闹钟具有可整点报时与定时闹钟的功能。 -EWB done by the multi-function digital clock oscillator output stable high frequency pulse signal as a time reference. Frequency Divider output by the standards of seconds pulse, aged 60 seconds to counter-counter rounding, Counter-to-60-hour counter rounding, by the Counter-hour "12 over a" law count, Counter by the decoder to display; Counting errors school circuit can be used for schools, school hours, school seconds to play : The alarm clock can be made with whole point regular alarm clock and timer functions.

说明：  逆变v/f控制，输出电压稳定，pscad仿真(Inverter v/f control, stable output voltage, PSCAD simulation)

简单的三相电流滞环控制模型，完整演示了滞环控制的方法及特性，适合初学者(Simple three-phase current hysteresis control model, a complete demonstration of hysteresis control methods and characteristics, suitable for beginners.)

说明：  通过移相，可实现三相桥并联出十二脉波整流。(By phase shifting, 12 pulse rectification can be realized by three-phase bridge in parallel.)
