- two tubular drive actuators having a space equivalent to that of conventional pneumatic assistance cylinders, each of the actuators being equipped with an engine electrical and being arranged for example in parallel pneumatic cylinders or instead thereof.
- an H-bridge comprises four switches arranged in a substantially H-shaped form, the motor to be controlled being located in the middle of the four switches and controlled as a function of the on or off state of the switches.
- this configuration leads to a large footprint due to the number of components required, which also leads to poor heat dissipation. It is also known to control several DC motors from only one H-bridge. However, this configuration does not allow independent control of the different motors. Now some applications, such as, for example, the opening or closing of a trunk, require independent and simultaneous control of each engine to allow effective actuation of the trunk and to avoid a torsion movement on the trunk.
- the invention therefore aims to overcome these disadvantages of the prior art by providing independent and simultaneous control of several engines in a simple and inexpensive way.
- the aim of the invention is to provide a control circuit for a plurality of DC motors able to be controlled independently of one another, comprising for each motor an H-bridge composed of a first branch and a second branch for controlling the associated motor characterized in that said second branches of the H-bridges are made by two switches forming a common branch of all the H-bridges and sized to receive a current equivalent to the sum of the motor currents so said motors can be driven simultaneously and independently by the application of control signals associated with the first branches.
- the invention also relates to a control circuit of which all the H bridges are in the same housing.
- each switch of the first branches of the H bridges is adapted to receive an associated PWM pulse width modulation signal.
- the PWM signals are independent of each other.
