2.2.1. Controlled by train wave
Definition : 2.2.1.1. Controlled law
The "Inter" switch is controlled according to a TCycle cycle. We choose TCycle in multiples of T From 0 to t1 Inter is closed =>
from t1 to TCycle Inter is opened =>
The maximum power is :
|  |
 | The mean power in R is :
Pmoy is linear and function of the ratio
|
Method : 2.2.1.2. Use of wave train dimmer
This type of control is mainly used in resistance heater control.
Note : 2.2.1.3. Design
The witch can be :
A contactor if the switching cycle
is > 1 min.Thyristors otr Triac if teh switching time
is < 1min. (Static contactor)
