PROCESS BY WHICH ALTERNATING CURRENT IS CHANGED TO PULSATING DIRECT CURRENT
A/C ( UNRECTIFIED)- FREQUENCY 60 Hz
60 NEGATIVE PULSES/SEC
60 FULL CYCLES
D/C HALF-WAVE – 60 POSITIVE PULSES/SEC
NEGATIVE PULSES ARE SUPPRESSED
D/C HALF-WAVE – 120 POSITIVE PULSES/SEC
D/C 3 PHASE 6 PULSE – 6 PULSES/CYCLE
D/C 3 PHASE 12 PULSE – 12 PULSES/CYCLE
3 PHASE WITH LONGER EXPOSURE TIMES
# OF DASHES = TIME (SEC) x 60 PULSES
# OF DASHES = TIME (SEC) x 120 PULSES
DEG. OF ARC = 360°/ sec x TIME (sec)
