Design of magnetically insulated transmission line oscillatorwith high efficiency operating at high input voltage

In order to get higher output power and higher efficiency, a new L band magnetically insulated transmission line oscillator(MILO) with a high operation voltage (700 kV) is designed based on the theoretical analysis and PIC simulation. From the simulation, an average output power of 11.2 GW with an efficiency 20.1% is got with an input power of 55.7 GW. The efficiency of the MILO is higher than that of traditional MILO with a lower operation voltage. Different from the lower operation voltage MILO, the new MILOs efficiency is not highest at its operation voltage but increases as the input voltage rises. This phenomenon is explained and it is concluded that with a proper design, high operation voltage MILOs would achieve higher efficiency and higher power along with increasing the voltage.
