Electric Bridge Transducer Driver or Amplification Circuit of Constant Current Drive
Circuit's Functions It's common that the strain gauge, magnetic resistance components, semiconductor pressure sensor etc. work in bridge way.This circuit uses MA constant current to unbalance the sensor and uses amplifier to receive.Sensor adopts diffused pressur sensor P-3000S-102G and its voltage range is 0~1KG/CM2. Circuit's Work Principle OP amplifier A1 is constant current output circuit and the magnitude of the current is determined by reference voltage,VZ and sensing resistance.This circuit uses the maximum magnitude of the variable voltage or the OP amplifier output gets saturated,which makes the circuit unstable.

Push-pull Type DC/DC Converter Circuit

Published:2011/7/7 16:20:00 Author:Michel | Keyword: Push-pull Type, DC/DC, Converter Circuit

The push-pull type DC/DC converter circuit is shown as above.Among them,transformer T1 acts as isolation and energy transmission.When switch tube Q1 turns on,transformer T1's windings works and it couples with vice side Ns1 winding.When switch tube Q1 turns off,Np1 releases energy to Ns1 and vice versa.The vice edge of rectifier circuit on output end is composed of flow inductor Lo and VD1, VD2.In the circuit design,both ends of switch tube should set RC absorbing circuit to the peak surge which is produced when the switch tube turns off.
