【摘要】 根据在野外使用微波炉的需求,采用直流供电、全桥逆变、高频升压的方式设计了一种新型野外用微波炉。采用UCC3895作为移相控制芯片驱动全桥逆变电路,同时具有过流、过压保护电路,可有效确保磁控管的稳定运行。该野外微波炉避免了家用微波炉采用直流电源供电时要另加逆变控制器的麻烦,实现了野外微波炉的高效率、小型化和便捷化。更多还原

【Abstract】 According to the requirements in the microwave oven outdoors,a new microwave oven outdoors is designed in the way of DC supply,bridge inverter and high-frequency booster.The phase-shifted chip UCC3895 is taken to control the full bridge invert circuit,the over-current protection circuits and over-voltage protection circuits ensure the magnetron′s normal operation.The microwave oven outdoors avoid the trouble that an inverse controller is needed when the conventional microwave ovens use DC power supply,the high efficiency,miniaturization and facilitation of the microwave oven outdoors are achieved.更多还原
