Applying Closing Phase-Angle Control Technique in Bounce Reduction of AC Permanent Magnet Contactor

Table 1

Comparisons of average bouncing duration of a pair of contacts after collision for both AC PM contactor and AC EM contactor.

Applied AC voltage source	Average bouncing duration (ms)
(Nominal value equals 220 V)	EM contactor	PM contactor
85%	1.556	0.832
100%	1.568	1.012
110%	1.620	1.088
Percentage of bounce reduction	38.19%
