The physiotherapy driver system comprises a main control chip, a signal generation circuit, a MOS tube switch network module, an LCC resonant network module, and network optimization and its matching circuit. The method adjusts the parameters of the LCC resonant network to match the loaded parameters of a corresponding ultrasonic transducer, so that the output of an entire system is optimized. the ultrasonic transducer operates in a resonant frequency range, so that the driver and the ultrasonic transducer are optimally matched, the energy conversion efficiency is effectively improved and the output of the ultrasonic amplitude is increased, the heat generation is small, the reliability and stability of a driver are effectively improved, the driver can continue to operate safely and stably, a more accurate optimization model is provided, the parameter design is relatively simple, the voltage amplification factor is further improved, the physiotherapy effect is improved, and the system facilitates widespread use.

Description

technical field [0001] The invention relates to the technical field of ultrasonic circuit driving, in particular to a physiotherapy driver system based on high-frequency ultrasonic waves. Background technique [0002] Ultrasound therapy is a technology that uses the effect of ultrasound on biological tissues to improve the condition of human tissues. When ultrasonic waves act on the human body, it will produce physiological effects such as thermal effects, mechanical effects, cavitation effects, thixotropic effects, and diffusion effects, which can be used for adjuvant treatment of cardiovascular diseases, limb movement disorders, and soft tissue contusions. Therefore, research on ultrasound-assisted therapeutic techniques has important research significance. [0003] Current research on ultrasonic physiotherapy drivers includes: driver architecture, resonant network, and power characteristics. The resonant network is used to improve the working characteristics of the tran...

Problems solved by technology

For the parameter matching and optimization of the resonant network, at present, most of the domestic and foreign countries still use empirical or manual debugging methods, which take a lot of time and cannot obtain the optimal matching parameters. Existing ultrasonic physiotherapy products have high cost, waveform distortion, Disadvantages such as non-adjustable power
