Abstract
The present description concerns a method of controlling at least one switch (TH), including: the reception of signals (S3-i) having between one another at least one phase shift representative of a desired state of said at least one switch; the obtaining, from said signals, of a value (Si) representative of the desired state; and the application of the representative value to said at least one switch.
Claims19
Method of controlling at least one switch, comprising:
- the delivery, by a transmitter module and from a first square pulse signal, representative of the desired state of said switch and having cycles repeated at a switching frequency, of second square pulse signals all having a same frequency, greater than the switching frequency, said second square pulse signals having with respect to one another at least one phase shift having a value which is a function of the state of the first square pulse signal;
- the transmission of said second square pulse signals through capacitive elements delivering phase-shifted signals;
- the reception, by a receiver module, of the phase-shifted signals reproducing said at least one phase shift;
- the verification, by the receiver module, of a valid or invalid state of said at least one phase shift;
- the obtaining and the storage, when the state of said at least one phase shift is valid, of a value from said phase-shifted signals, said value being representative of the desired state of said at least one switch;
- and
- the application, to said at least one switch, of the obtained representative value if the state of said at least one phase shift is valid or of the stored representative value if the state of said at least one phase shift is invalid.

Circuit for controlling at least one switch comprising:
- at least one driver of application, to a control terminal of said at least one switch, of a square pulse control signal having cycles repeated at a switching frequency;
- and
- a module for receiving phase-shifted square pulse signals, representative of a desired state of said at least one switch, the frequency of the cycles of said phase-shifted signals being greater than the switching frequency and at least one phase shift between said phase-shifted signals having a different value according to the desired state of said at least one switch, the receiver module delivering, to said driver, a value corresponding to a value obtained and stored from said at least one phase shift when the state of said at least one phase shift is valid and to a stored value if the state of said at least one phase shift is invalid.
