TRANSFER/SEPARATION CORONA CIRCUIT
When the Start key is pressed, the main board LOW
sends signals to
energize the power pack for the transfer and separation coronas. The power
pack has a dc to dc converter and a dc to ac inverter. The dc to de converter
changes +24 volts to +5.6 kilovolts for the transfer corona. The inverter
changes +24 volts to 5.0 kilovolts ac (500 Hz) with a negative dc bias (about
-90 V) for the separation corona.
