Current supply control for microwave tube - has switch regulated by control signals from counter, blocked when current integral reaches limit

摘要

The device is designed to ensure a supply of electrical power to a microwave tube. The power device has a switch (17) which closes the circuit for specified time intervals in accordance with periodic control signals. Each control signal is counted by a counter (22). A current signal is generated and integrated, and when the current integral reaches a limit, the switch (17) is blocked until the counter (22) has reached a specified number. The system incorporates a transformer (12) with a single primary winding and two secondary windings (14, 15).
