Definitions

  • the drive-on signal 127 transits high as shown by reference number 221 because the primary winding voltage signal 195, after being scaled by the scaler 113, is less than the flyback limit voltage 188 provided at the output 187 of the flyback limit voltage reference 185.
  • the drive-off signal 163 and the early current signal 177 remain unchanged as shown by reference numbers 223 and 225 respectively.
  • the primary winding current signal 193 continues to increase, building the current sense voltage 149 across the resistor 147, until it exceeds the over current limit reference voltage 161 as shown by reference number 239 at a reference line 237.
  • the drive-off signal 163 at the output 157 of the over current comparator 151 transits low, as shown by reference number 243.
  • This drive-off signal 163 then forces the flip-flop 129 into a reset state providing a low state to the input 139 of the logical AND gate 137. This action results in a transition low of the command signal 145 as shown by reference number 241.
  • this cycle will repeat, maintaining the current through the primary winding 103 at a predetermined constant average level 250 by repetitively providing an increasing current through the primary winding 103 when the flyback sense voltage 118 exceeds the flyback limit voltage 188 and decreasing this current through the primary winding 103 when the current sense voltage 149 exceeds the over current limit reference voltage 161.
