Latest Patents

Shuji Sunano holds a patent for a unique choke coil design. The patent describes a system where two coils, 3a and 3b, are wound over adjacent portions of a first magnetic core that has two closed magnetic circuits, along with a second magnetic core. The winding directions of the two coils are configured to cancel each other's magnetomotive forces in the second magnetic core. This innovative design effectively decreases the higher harmonics of the input current from the power source circuit while also reducing noise between the line and the ground. Thus, the choke coil serves dual purposes as both a choke coil and a noise filter.
