The single terminal flyback switch power supply circuit

Published:2011/6/21 6:58:00 Author:qqtang | Keyword: single terminal, flyback switch

The single terminal flyback switch power supply application circuit is shown in figure 3. The so-called single term means the magnet circuit side of the core in the high-frequency transformer. The so-called flyback means when the switch VT1 is conducting, the inductive voltage of primary coil in the high frequency transformer T is positive in the upper part by passive in the lower part, the rectifier diode VD1 is blocked and save power in the primary coil. When the switch pipe VT1 is blocked, the power stored by the primary coil is delivered to the load after it has been past the coil, rectified by VD1 and filtered by capacitor C.   (View)

The simple but special regulated circuit

Published:2011/6/21 2:14:00 Author:Seven | Keyword: regulated circuit

The simple but special regulated circuit: In some conditions, if there needs a regulated circuit while it is running with load, as the control and detector, this circuit will seem brief and convenient. By adjusting the ratio of R1 and R2, the input voltage of the regulated module can be changed, the value of C1 is relative to the loading. A. If the single way thyristor is switched in to dual way thyristor, the circuit will be simpler.   (View)

The 9V battery strainmeter signal adjusting circuit

Published:2011/6/20 22:21:00 Author:Seven | Keyword: 9V battery, strainmeter signal

The 9V battery strainmeter signal adjusting circuit is shown as above.Notes: this is a 9V battery strainmeter signal adjusting circuit, the sampling circuit offers the low average working current of 650μA. As ΔV/ΔT jumps in a high order, the RC net composed of 4.7KΩ and 0.01μF is used to protect the reaction bridge, which avoids the long-term drifting.   (View)
