16.02.2017 Some diagrams may show SCR Diode Diode SCR, but it works either way. This string of devices makes up 1 output phase, so now put 3 of these strings side by side for a 3 phase output. All the Anodes across the top to plus bus, and all the Cathodes across the bottom to the minus bus. OK.

SCRs are unidirectional (one-way) current devices, making them useful for controlling DC only. If two SCRs are joined in back-to-back parallel fashion just like two Shockley diodes were joined together to form a DIAC, we have a new device known as the TRIAC: (Figure below). The TRIAC SCR equivalent and, TRIAC schematic symbol

The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators). Electrons pass by the openings to these cavities and cause radio waves to oscillate within, similar to the way a whistle produces ...

The AC voltage is fed from the transformers to a set of ultrafast diodes to rectify the voltage which is stored and filtered by the two capacitors. A control circuit is used to sense when the output voltage provided and when the output gets short circuited the voltage drive to the output is removed.
