The switching output circuit of ultrasonic oscillator

Published:2011/6/21 6:33:00 Author:Lucas | Keyword: switching , output circuit , ultrasonic oscillator

The power + U of output circuit is the DC voltage which is rectified, smoothed form the AC power. The control circuit uses +12 V power supply, therefore, it uses of transformer Tl to make the electrical isolation between low and high voltage. The inputs A and B of control circuit is the pulse voltage which is from the the 180 ° phase difference of integrated controller output, then the voltage amplified by VT1 and VT2 to drive MOSFET tubes VT5 and VT6 by passing transformer Ti. The duty cycle of VT5 and VT6 gate drive signal is approximately 45%, and the peak of gate voltage U (GS) is about lOv.   (View)

Broadband linear detector circuit

Published:2011/6/20 8:43:00 Author:Lucas | Keyword: Broadband , linear, detector circuit

Broadband linear detector circuit is shown as the chart 1-27. It is used in the millvoltmeter and other linear detector circuits with the bandwidth in 10MHz. Uol output is the DC signal, and Uo2 output is the monitor signal. μPC53 is the broadband operational amplifier, and the output is amplified by the differential amplifier composed of VTl and VT2. The differential amplifier requires a higher supply voltage (+24 V). VD1 and VD2 are the the detector diodes, which are connected in the negative feedback circuit.   (View)

Dual wave linear detector circuit

Published:2011/6/20 8:37:00 Author:Lucas | Keyword: Dual wave , linear, detector circuit

Dual wave linear detector circuit is shown as the chart. In the circuit, Ui is the AC input signal, and U is the rectifier output signal. In the positive half-cycle of AC input, A1's output is positive. As VD1 knife is positive bias, A2's input is positive, and its output is also positive, and it makes a feedback on A1 by R2, RPl and Rl, so A2 becomes a noninverting amplifier with the gain in 1; in the negative half-cycle of AC input, Al's output is also negative, and VD1 is anti-bias, then A2's inverting input is 0, that is, the working status of the inverting amplifier.   (View)
