Fast Bias Drop Circuit


 


How it works


 



  • Input signal closes relay

  • HV power supply charges capacitors

  • Input signal to relay removed, relay opened, HV supply can be removed

  • Emitter retracted, position sensor sends pulses to One Shot circuit

  • t_d later, One Shot circuit outputs signal to HV MOSFET circuit

  • signal goes through ISO amp, op amp amplifies signal

  • signal goes to MOSFET, allows current to flow to quickly change emitter bias


 


Other Stuff



  • "Pause" one shot blocks new pulses for 1 second after first pulse

  • "Length" one shot stops stignal to HV MOSFET circuit after 1 second

  • Timing of one shots can be changed by changing potentiometer resistance

  • 35.4 kOhm corresponds to t_d=21.6 ms, should
