Abstract

PURPOSE:To reduce the capacitance of a capacitor and to cut off power supply noise, by using a set position of a tuning circuit of a receiving side as the power supply line side. CONSTITUTION:A receiving-side tuning circuit utilizing a power supply for home use used for a remote controller and an interphone is constituted to be tuned to an AC line 2. Further, diodes 5, 5 are connected to a circuit 1 in polarity opposite to each other in the primary winding. Through the constitution like this, the capacitance of the capacitors 4, 4' is decreased and noise from the power supply is cut off.

It was not possible to block out noise from the power supply, and in the case of a remote controller, it was limited to the capacitor capacity and could only operate 4 to 5 household equipment units, and in the case of an intercom, It was not possible to block out the noise from the power supply, making it extremely difficult to hear.The present invention aims to eliminate the above-mentioned drawbacks, reduce the capacitance of the capacitor, and further block out the noise from the power supply. This purpose was achieved by adopting a configuration of primary side tuning, which was completely unthinkable in the past, and by arranging two diodes, one in the forward direction and one in the opposite direction.

It can operate several times as many units as conventional devices, and the intercom can cut off noise from the power supply and transmit clear voice. Since the capacitance of the capacitor can be small, this invention is extremely advantageous in terms of cost and performance, and has a wide range of applications.
