Abstract: In the given paper the model of the miniature modulator for microwave devices is observed. The modulator consists of the master oscillator, which provides four series of the impulses, and of the inverter commutated with the surge generator providing a plate supply of the load. The pulsing plate supply of the load is stabilized by the current regulator on the unipolar transistor. The control and check unit realize the general control of the modulator. The optimal characteristic of the work of a magnetron is provided by the 16-digit microcontroller.

Keywords: microwave device, surge generator, sheath current, current stabilizer, magnetron, microcontroller, inverter, converter, bridge circuit design, pulsing high-voltage transformer.
