The resistor (parallel with the coil)
For efficient action, the resistor must be of the same order of magnitude as the coil resistance. A resistor 1.5 times the coil
resistance will limit the surge to 1.5 times the supply voltage. Release time and opening speed are moderately affected. The
major problem is the extra power dissipated.
Semi-conductor devices
The diode
It is the most simple method to totally suppress the surge voltage. It has the major disadvantage of the higher reduction of
contact opening speed. This is due to the total recycling, through the diode, of the energy contained in the coil itself. The
following measurement is performed once again on the same relay. Operation times are given by the upper curve:
- time to start the movement 14ms
- transfer time 5ms
These times are multiplied by a coefficient from 4 to 8.
The lower curve shows the coil current. The increase prior to NO contact opening indicates that the contact spring dissipates
its energy. At the opening time the current becomes constant as a result of practically zero opening speed.
Due to this kind of behavior, this type of suppression must be avoided for power relays. For small relays which have to switch
low currents of less than 0.2 A, degradation of life is not that significant and the method may be acceptable.
