Description

452836 V. Description of the invention (l) The closing device of the present invention ", when the traditional electrical terminal of the conductor switch is short-circuited or the switch is connected to the switch with a mechanical life and the current is not good, the negative current is not allowed to exceed the limit or the circuit breaker is connected to the motor. As a result, the frequency converters such as: spinning coils, transmitters, etc., are currently low in pressure-reducing power, harmonizing with the Siemens rating of Germany, but the traditional aspects of torque are related to a kind of "especially a kind of In the case of a motor switchboard failure, the fuse switch, and the breaking speed. In particular, because the load is easily damaged by 10 microseconds, it cannot be operated in the production line system. Once it is broken, the steel rolling system is taken into consideration. The switching circuit of the motor is used for the brake fluid. Due to the high wave, the starting and the American AB start torque cannot be obtained by the fan and the water pump. The AC power supply can be switched at any time. The ultra-fast semiconductor is turned off at any time.

The regulator and pressure regulating fluid (SC ') are delayed due to the delay, so the motor is not good. For example: The flow is 500%, which is suitable for the low start to severe limit to close. 0331.ptd Page 4 4 528 3 6 The present invention People are embarrassed by the shortcomings of the use of traditional electric motor switchboards and controller switches. Therefore, they are beginning to improve their courses and make up for their shortcomings in order to find a reasonable solution. After numerous studies and analysis, , Design, and finally completed the present invention "AC power ultra-fast semiconductor switching device at any time." And the purpose of the present invention is to ultra-fast semiconductor switching device ", the first and second semiconductor element terminals of the control type are connected and turned on together, and Each parallel number is input to the gate microseconds of these semiconductor elements), and the alternating current conductor element constitutes a freewheeling current that can be quickly switched on and off at any time before it is cut off. That is, the control function is used to replace the traditional circuitless device, overloaded electro-discharge and fuses, etc., as a soft start function of the motor. And high efficiency. Another object of the present invention is that it is fast, no arc occurs, and the special power supply can be operated up to tens of thousands of amps. Dozens of times the cost. And it uses digital to be able to communicate with a computer for centralized control. The time is mainly connected in series to the AC power of each phase, and the second semiconductor element can be connected to the opposite diode to control the pole to quickly switch on the AC power (when the source is cut off, the load is matched). The second half is 'to avoid the occurrence of ultra-high voltage, so the power supply is not necessary when the voltage crosses zero. The 0 series semiconductor switching device can cooperate with simple fuse switch, electromagnetic switch, leakage current', and can be equipped with additional software and hardware, power factor Controller and voltage regulator speed operation. The overall switching speed of the semiconductor switching device is small and the service life is long. It only needs 15 volts. Compared with traditional switchboards, it can save operation. Simple, reliable and high-efficiency control function. 6 3 8 2 5 4 It takes into account the use of a set of body hand reshaping techniques to make use of it.
