Abstract
A fault-tolerant control system facilitates the closed loop control of a magnetron. The control system includes a transformer assembly for applying peak current to a magnetron, a pulse-forming network that conditions a transmit pulse, and a control circuit for adjusting the peak current applied to the magnetron. The control circuit includes a sample and hold circuit for comparing a signal representative of a detected peak current to a desired peak current level. The sample and hold circuit is coupled to a digital up/down counter circuit, and the output of the counter circuit is utilized to adjust the charge voltage of the pulse-forming network.
