Circuit Board 1000W PCB Ultrasonic Generator Parts Circuit Board For Ultrasonic Cleaning Machine

The power amplification module of the ultrasonic PCB power circuit board includes field-effect transistor drivers A1 and A2. A1 and A2 drive the rear circuit to work when the mode selection signal MODE is low level. The rear circuit of A1 and A2 is the excitation end circuit P1 and the bridge amplifier circuit P2. The excitation end circuit P1 contains high-frequency high-power field-effect transistors D1-1 and D1-2, D1-3 and D1-4, which respectively form two groups of totem poles. The output of the two groups of totem poles is to transformer L1, In the resonant state, the output is output backward to the amplifier circuit at the output end of the later stage. The driving square wave generated by the excitation end is divided into four drives through the high-frequency transformer T1, corresponding to four high-frequency high-power field-effect transistors: D2-1, D2-2, D2-3, and D2-4. 3. The high-frequency high-power ultrasonic driving device as claimed in claim 1, characterized in that the output resonance matching module is composed of a frequency selection network composed of capacitors and inductors.
