Control device variation of power and / or speed of a load.

摘要

The invention relates to a control device VARIATION OF POWER AND / OR SPEED LOAD (2) AS AN ASYNCHRONOUS MOTOR, SYNCHRONOUS, UNIVERSAL, a transformer, an inductance of a capacitor or a resistor, THAT comprises a switch (5) placed on a PHASE (4) A SUPPLY CIRCUIT alternating current (3) single or polyphase, the latter being SWITCH (5) associated with management means (6) RATIO CICLICO ALFA / 7 WHERE ALFA is the time of opening and closing the circuit (3) by the switch (5) and (T) PERIOD PHASE (4) on which the latter is in place. In fact, the switch (5) is of the type BIDIRECTIONAL TRANSISTOR MOS, IGBT or bipolar, WHILE THIS SWITCH (5) ATTACHED TO MEDIA CONTROL TIME SWITCHING (9) TYPE DRIVER IN ORDER TO EXTEND INCLUDING sWITCHING TIME IN SO CLOSE it is located at a 10 microseconds between 1 millisecond area.
