HV Switching Waveforms and Operation

HV506

To drive a TFEL row with a negative pulse: The desired sink SCR

is enabled and VSS is connected to -HV via a current limited

switch. After holding the output at the -HV level, the switch is

opened in order to set the sink SCR current to zero. The row is

then discharged through a discharge diode when D2 is switched

to GND. The application of a positive pulse to a row operates in

a similar manner using the selected source SCR and D1.
