CA 2113440

A solid-state motor power control (40) for portable paint pumps having a MOSFET power control device (50) operated from a solid-state electronic control circuit wherein the control circuit utilizes an operational amplifier (62, 68) to selectively operate as a switch driver in a first state and as a linear gain amplifier (62) in a second state. The solid-state control circuit has compensation means for compensating the MOSFET (50) for motor load variations in a pump motor (44) connected to the output of the solid state motor power control (40).

Commande de puissance de moteur à semi-conducteurs (40) pour pompes à peinture portatives munies d'un module de commande à transistors MOS (50) à circuit de commande électronique à semi-conducteurs utilisant un amplificateur opérationnel (62 et 68) pour fonctionner comme commande de commutateur dans un premier mode et comme amplificateur linéaire (62) dans un deuxième mode. Le circuit de commande à semi-conducteurs est muni de dispositifs de compensation connectés du côté sortie de la commande de puissance du moteur à semi-conducteurs (40) pour compenser les variations de charge du moteur (44) de la pompe.
