In the present day of energy saving, the high-intensity ultrasonic homogenizer system has special interest as the system making the COM (Coal-Oil-Mixture), gasohol (gasolene-alchohol mixture) and emulsified fuel (gasolene-water mixture) . As its electrical power supply, the new application of thyristorized high-power inverters for an output frequency range in the extent of 15KHz to 30KHz are hopeful from whole points of view such as low cost system, high-power output adaptability, maintenance free, easiness of control procedure and so on.<BR>This paper describes a steady-state performance analysis considering overlapping commutation-mode of high-frequency inverter using reverse-conducting thyristors (abbreviated by RTh type inverter) . The steady-state characteristics and operation of RTh type inverter for driving high-intensity ultrasonic homogenizer system are quantitatively discussed in comparison with the characteristics on the basic type of series-inverter. The inverter circuit is analyzed with R-C load modelling the ultrasonic transducer systems.
