Abstract The authors have developed a new
power control method, in which a high-voltage switch is used, and the output
power is controlled by changing the interval of half-wave current flow time
in the secondary circuit of the transformer. The switch is actuated at
zero-current (intermittent of had wave current) by a controller and a
phase-control device. With this method, there is no rush current, no electric
arc and little magnetron filament temperature change, which results in the
increased life of the magnetron. |
