Full-Wave AC Switch II (MEC138E)

This article was written based on my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. The described circuit can be used to turn on and off loads powered from the AC power grid. This circuit has the same applications as MEC137E.

The circuit shown in Figure 1 is another way to connect the load in a full-wave switch using an SCR. The circuit operates in the same manner as the previous one.

See MEC138E for more information about the diodes. The SCR must be mounted on a heatsink according the power of the controlled load.
