Drive circuit for large-power supersonic transducer array

The drive circuit for driving electrically the supersonic transducer array in high-power supersonic extracorporeal-focus thermotherapeutic machine includes one signal source, power drive units connected to the signal source and output transformers connected through the primary winding to power drive unit. The secondary windings of the output transformers are connected serially and connected with the ends of the transducer array through the single output interface to constitute one driven transducer array. The power drive unit adopts C-type push-pull circuit and the signal source outputs two channels of signals with 180 deg phase difference and duty cycle smaller than 0.5. The circuit is simple, practical and reliable.
