The Two-anode thyristor controlled load switch (Two-anode MOSFET thyristor). The circuit has input characteristics of a high-speed thyristor, but the losses on its open switching elements are almost two orders of magnitude lower than for conventional thyristors. In addition, the proposed load switch has, in contrast to the conventional thyristors, two outputs. First output is in the switched-on state and the second output is in the switched-off state. These outputs are switched over according to the thyristor switching.
When using a Two-anode MOSFET thyristor in an alternating current network with a power controller in the circuit of one of its channels, the unused sine wave sections in case of classical thyristors will not be lost and can be used in the circuit of its second load channel.
The use of MOSFET transistors in the proposed version of a two-anode thyristor provides its higher switching performance, extremely low losses and high input resistance. These features and parameters of the two-anode MOSFET thyristor allow it to be approximately an ideal switching element.
