出来るようにしたものである。Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention connects two bidirectional thyristors in series and parallel to an electric blower, so that even if the power of the electric blower is large, the bidirectional By controlling the junction temperature of the thyristor to below the set value, it prevents element destruction, eliminates problems such as conventional contact failure, and allows the use of low-power and inexpensive temperature control elements themselves. This is how it was done.

Moreover, the bidirectional thyristor 102,
103 has heat dissipating fins 104, 1 as shown in FIG.
A temperature sensor is attached to each of the radiation fins, and the output of the temperature sensor is input to a temperature control circuit 107, and a gate control circuit 108 controls both of them so that the temperature of the radiation fins is constant. According to the graph shown in Fig. 5, which controls the switching of the tropic thyristor, the temperature of the radiation fin of the bidirectional thyristor is at the upper limit T1.

By repeating such control, the temperature rise value is controlled within a constant range, and the life of the element itself is extended and reliability is also improved. Furthermore, there is an advantage that the radiation fin itself can be made smaller. As described above, the practical value of the present invention is extremely large.
