高可靠性真空微波功率模块保护电路OA北大核心CSTPCD

A high reliability high voltage power supply protection circuit is designed,which is suitable for vacuum microwave power module.The PSpice simulation software is used for the circuit simulation to simplify the circuit design and optimize the circuit parameters.The testing system is established with a traveling wave tube,a circuit board is designed for the actual testing,and the instruments such as an oscilloscope are used to verify the effectiveness of the protection circuit.In allusion to long-term and high-intensity working conditions,the circuit design includes bus current overcurrent protection circuit,spiral wire current overcurrent protection circuit,and power outage protection circuit.When working abnormally,the module can be closed in a timely and effective manner to prevent damage to components.The simualtion results show that the designed protection circuit can improve the reliability of microwave power module,reduce the development cost and prolong the service life.
