ABSTRACT:
The invention relates to a speed controller comprising:at the input, a rectifier module (12) in order to generate, on a power bus (10, 11), a direct voltage from an alternating voltage available on an electrical supply network (A),a bus capacitor (Cb) connected between a positive line and a negative line of the power bus,an inverter module (13) supplied by the power bus and controlled to deliver an alternating voltage to an electric load (2),a device (14) for protecting the controller consisting of a first electronic switch of the JFET transistor type (T1) and a second electronic switch (T2) mounted on the power bus, in parallel with the JFET transistor (T1).
