| Outline of Final Research Achievements |
A gate drive signal transmission system for next-generation power electric circuits using surface acoustic wave filters was proposed. Since SAW filters fabricated on lithium niobate wafers can work in the range of ~1000 degree Celsius, receivers can be located near motors and engine room, such as high temperature conditions for reducing energy loss and EMI.
We designed a transmitter and receiver and fabricated 4-channel SAW filter arrays on lithium niobate wafers suitable for the proposed system. The 3-level inverter system based on the proposed system was demonstrated without problems.
These results indicate that the proposed system design can be used to the multi-level inverter system.
