The design based on the numerical analysis of the SEPP-ZCS inverter for high-intensity ultrasonic homogenizer

The inverter circuit for high-intensity ultrasonic generator is demanded to work over a wide range of load, because the ultrasonic transducer has extremely high mechanical quality factor and slight difference of load condition to it greatly influences its operation. This paper proposes a method of circuit design based on the numerical analysis to achieve zero current soft switching operation in any load condition of the inverter, to suppress switching stresses, and to reduce distortion factor of inverter output voltage.
