- an emergency power supply is implemented in the event of a failure of the electrical distribution network (alternative 50-60 Hz) and in the event of energy demand resulting from a command to be executed by equipment.
- This emergency power supply is produced by means of an assembly whose structure is shown diagrammatically by the first three figures of the cited patent application.
- This supply allows, for example, the supply of a drive device for a garage door as described in the patent.
- US 6,025,785 that is to say comprising an AC motor.
- the assembly comprises a device for charging a battery, a battery, a DC-AC converter but also a control unit connected to a mains voltage detector and power switching means making it possible to connect the output of the assembly to the voltage.
- the motors used in building equipment drive actuators are of the DC type and are supplied from the network by means of an AC-DC converter comprising a rectifier and a step-down voltage.
- EP 1 078 436 discloses an electrical installation comprising an electrical device intended to be connected to the AC network and provided with a step-down converter for supplying an electrical circuit with a very low voltage direct voltage.
- the installation includes a backup device fitted with a Low Voltage battery (100 - 120 V or 240 V) to supply the electrical device in the event of a network failure.
- the electrical installation according to the invention is characterized by the characterizing part of claim 1.
- FIG. 3 is a detailed diagram of the structure of the power supply device according to the invention.
- FIGS. 4a to 4e are diagrams of different electrical structures which the means for converting the voltage of the storage element into an output voltage of the device can present.

- Figure 6 is a detailed electrical diagram of a converter for powering the actuator motor.
- the installation 1, shown in FIG. 1, includes an actuator 10 for the operation of mobile building equipment 20 such as a garage door, a shutter, a blind or the like, a remote control 30 for controlling this actuator 10 and a backup power supply device 40 for supplying the actuator with mains voltage (AC-H, AC-N) or for generating a supply voltage for the actuator in the event of a fault in the network.
- an actuator 10 for the operation of mobile building equipment 20 such as a garage door, a shutter, a blind or the like
- a remote control 30 for controlling this actuator 10
- a backup power supply device 40 for supplying the actuator with mains voltage (AC-H, AC-N) or for generating a supply voltage for the actuator in the event of a fault in the network.
- the actuator 10 mainly comprises a DC motor 11, a step-down converter 12 of the synchronous type and means for switching 13 making it possible to apply the output voltage of a converter to the motor to make it rotate in the desired direction and also making it possible to short-circuit the motor when the latter is no longer supplied.
- the positions of the switching means 13 are controlled, by means of the control line 16, by a control circuit 14, for example provided with a radio receiver enabling it to communicate with the nomadic remote control 30.
- the orders Radio frequencies are picked up by an antenna 15.
- the radio link is bidirectional so as to be able to inform the remote control of the correct execution of the orders received, or for example, of a power supply fault of the actuator.
- the electric motor 11 is of the direct current type, preferably with permanent magnets.
- UDC its nominal voltage which is typically 12 V, 24 V, 36 V or 48 V.
- the actuator is designed to be directly supplied by the alternative electrical power distribution network, for example 230 V, 50 or 60 Hz, or even 110 V, 50 or 60 Hz, by means of two mains terminals 17 constituted for example by an electrical outlet.
- the step-down converter 12 makes it possible to adapt the network voltage to the nominal voltage of the motor.
- the step-down converter 12 is preferably of the synchronous type, that is to say it is a non-isolated AC-DC step-down converter, equipped with a rectifier followed by an energy storage element such than a capacitor and a controlled switch making it possible to establish a connection between the output of the rectifier and the capacitor. So when the voltage across one and / or the other goes below of given threshold (s), the switch is closed and, when the voltage across this capacitor reaches a sufficient value, and / or as soon as the output voltage of the rectifier rises above a given value , the switch is open. Depending on the arrangements, the controlled switch is closed once or twice by half-cycle of the mains voltage.
- Such devices are known for example from patent application WO 03/030344 by the applicant.
- the step-down converter can be chosen from another type than synchronous. In this case, it must necessarily include a first rectification stage as represented by the block 121 of FIG. 1, and it must have a wide operating dynamic compared to the possible variations of the input voltage.
- an emergency power supply device 40 between the electrical distribution network and the actuator in order to ensure the supply of power to the actuator in the event of failure of the network.
- This emergency power supply device 40 includes an element 41 for storing electrical energy such as a storage battery.
- the nominal voltage of this storage element is of the Very Low Voltage type (for example 12 V or 24 V).
- An element of the Very Low Voltage type is understood to mean an element whose nominal voltage is less than or equal to 48V.
- This type of element makes it possible to guarantee low manufacturing costs and space requirements of the emergency power supply device although it requires a voltage conversion device 47 to charge the element thanks to the energy supplied by the network. .
- the fact of using a very low voltage emergency supply device considerably simplifies the electrical insulation constraints, which contributes to reducing costs. In this case, it is the two input terminals 42 of the emergency power supply device 40 which are connected to the network, while the output terminals 43 of the emergency power supply device 40 are connected to the mains terminals 17 of l actuator.
- the converter 12 is shown in detail in FIG. 2.
- a rectifying means 121 for example a Gra ⁇ tz bridge with diodes.
- the voltage at the terminals 17 rectified by the rectifying means 121 is then lowered by lowering means 122.
- the rectified voltage makes it possible to charge a capacitor 21 through a controlled switch 22.
- a current limiter 23 can be constituted by a simple resistance, but also by an inductive circuit.
- the voltage converter can have the structure shown in FIG. 6. This converter has two input terminals A and B to which an alternating voltage U is applied, for example the network voltage.
- the converter comprises an energy storage capacitor 61 supplied on the one hand by a first full-wave rectifier assembly 68 (diodes in Graetz bridge), via a switch 62, in this case a MOS or controlled field effect transistor. by a control unit not shown, and supplied on the other hand by the output of a second full-wave rectifier assembly 67.
- the input of the rectifier assembly 68 is connected between the input terminals A, B in series with a resistor 66 and the primary 651 of a transformer 65.
- the secondary 653 of the transformer is connected to the input of the second full-wave rectifier assembly 67, the output of which is connected to the output S of the voltage converter.
- the current in the switch 62 is limited by placing the resistor 66 and the primary 651 of the transformer in series. We are therefore in the presence of a highly inductive current limiter.
- FIG. 6 shows that in the case of a step-down converter 12 of synchronous type, the rectifier is therefore not necessarily placed as an input element of the converter.
- a mains synchronization control circuit 24 controls the closing of the controlled switch 22 when the voltage coming from the rectifier or the output voltage of the converter is less than a given threshold and controls the opening of the controlled switch when the output voltage has reached a given value or when the voltage from the rectifier becomes greater than a given value.
- a voltage detector 51 monitors the presence of a voltage on the electrical supply network and consequently controls the controlled switches 52a and 52b.
- the controlled switches 52a and 52b respectively connect: terminal 41a of the storage element to the output terminal 43a directly, and terminal 41b of the element storage at the output terminal 43b through the voltage conversion means 44.
- the controlled switches 52a and 52b connect the input terminals 42 of the emergency power supply device to the terminals 43a and 43b.
- the voltage conversion means 44 comprises an inductor 49 and a capacitor 48.
- the controlled switch 45 changes from a closed state to an open state, the voltage across the terminals follows a sinusoidal type growth to reach a double amplitude of the voltage delivered by the energy storage element 41.
- the time width of the pulse depends on the inductance and capacitance values of the elements chosen. It is conventional to close the switch 45 when the voltage across its terminals is zero, which eliminates any loss by switching. Waves are then obtained of the type shown diagrammatically in FIGS. 5a, 5b or 5e. If the switch 45 remains open longer, it is possible to obtain oscillations in the form of damped sinusoids, as shown in FIGS. 5c, 5d and 5f. Having negative zones is not a problem since they are then rectified by rectifier 121 of the actuator. If a MOS transistor is used to make the switch 45, the intrinsic source-drain diode suppresses negative half-waves.
- the operation, and therefore the shape of the waves of the output voltage is more or less influenced by the consumption of the actuator connected to the output terminals 43a and 43b.
- the synergistic effect between the actuator and the voltage conversion means can be used so that the functions of the inductor 49 and the capacitor 48 are performed respectively by the current limiter 23 of the converter of the actuator if it is of an inductive nature and by the capacitor 22 of the converter of the actuator, as illustrated in FIG. 4d.
- the lower terminal of the tripole 44 is not connected to terminals 41a and 43a.
- the controlled switch of the voltage converter is eliminated.
- the function of the switch 45 of the emergency power supply device is provided by the switch 22 of the converter 12 of the actuator.
- FIGS. 4a to 4e Any combination of the structures shown diagrammatically in FIGS. 4a to 4e is possible.
- the output voltage of the emergency power supply device is continuous, although the current supplied is not. It is also noted that the current supplied by the emergency power supply device depends directly on the consumption of the actuator, which acts, via the control circuit 24, on the activation frequency of the controlled switch 22 .
- a current sensor 50 shown in FIG. 3, makes it possible to supply the oscillator 46 with a current measurement which is used for controlling the controlled switch 45. It should be noted that this measurement is greatly simplified when the converter of the actuator is such as that represented in FIG. 2 or in FIG. 6. The current is absorbed intermittently and its approximate measurement can be carried out simply by determining the time of circulation of this current.
- the current sensor can simply consist of an opto-coupler, the light-emitting diode of which is placed in series on one of the output wires and whose transistor is connected to the input of a time measurement circuit of the microcontroller.
- the complementarity acts in particular when the converter has the structure shown in FIG. 2, with a highly inductive current limiter 23, and even more so when the converter has the structure shown in FIG. 6, the inductance of the primary winding 651 intervening strongly in the current limitation.
- the operating logic of the control circuit 24 can make the switch 22 permanently conductive in FIG. 2, or can make the switch 62 permanently conductive in FIG. 6.
- the voltage across the terminals of the current limiter becomes zero if it is purely inductive, which avoids an additional loss of voltage: the diagram therefore adapts naturally at the presence of a DC input voltage and of low value.
- a second variant of the emergency power supply device differs from the first variant in that the emergency power supply device does not include means for converting the voltage of the storage element.
- Such a variant having no conversion means raising the voltage of the storage element can be used when the voltage across the terminals of the storage element is high, and at least equal to or greater than the nominal voltage of the current motor.
- DC actuator In this case, the switch 22 can remain permanently closed if the voltage of the storage element is close to the nominal voltage of the DC motor.
- the advantage of having an inductive element 23 or 65 in the step-down converter is that it does not does not cause an additional voltage drop for a supply under DC voltage.
- a third variant of the emergency power supply device differs from the first variant in that the emergency power supply device does not include means ensuring recharging of the element 41 for storing electrical energy.
- the storage element not being recharged, it can be constituted by a storage battery but also by a battery or a set of batteries.
- a fourth variant of the emergency power supply device differs from the first variant in that the emergency power supply device does not include switching means 52 for alternately connecting the output terminals 43a and 43b to the terminals 41a and 41b or to the terminals 42.
- all of the actuator supply periods are made via the storage element without taking into account the presence or absence of voltage on the electrical distribution network.
- the structures of the various alternative embodiments of the emergency power supply device according to the invention have a simplified architecture compared to inverters type converters known from the prior art insofar as they have at most one controlled controlled switch 45 in frequency. Consequently at least one 41a of the terminals of the storage element is permanently connected to one 43a of the output terminals.
- the cost of producing the converter according to the invention is therefore lower than the cost of manufacturing an inverter.
- the voltage from a converter according to the invention is therefore not alternative, however, it allows the electrical supply of a actuator comprising a synchronous type converter and a DC motor.
- the output voltage delivered is of the pulse type, that is to say formed one or more pulses.
- the pulses are for example all positive and repeat at a frequency close to 100 Hz.
- the pulses can also be in the form of a first positive wave followed by a second negative wave, of lower amplitude. It can also be a decreasing wave train. Each group or train of pulses repeats at a frequency of 100 Hz when a large power is required to supply the actuator.
- the production of pulses can also be controlled by the current absorbed by the actuator, and therefore decrease spontaneously when the motor is not supplied.
- the voltage or current pulses supplied by the emergency power supply device can have their frequency directly fixed by the control circuit 24 of the controlled switch 22 in the case of FIG. 4e, or even in a similar case where the inductive element 23 would be replaced by the inductive element 49.
- FIGS. 5a to 5f give examples of waves delivered by an emergency power supply device according to the invention.
- very low loss circuits are chosen, with switching at zero voltage and / or at zero current. This is the case of pseudo-resonant montages.
- the latter is advantageously the battery of an automobile parked near the actuator, and the connection between the The actuator and the battery is preferably carried out using the cigarette lighter socket of the automobile.
- the two-wire connection cable therefore comprises a male cigarette lighter plug at one end and a female sector plug at the other end shaped to be connected to the mains terminals of the actuator.
- the actuator is a garage door actuator, and has a lighting lamp, it is useful that this lamp is automatically disconnected when there is power from the emergency power supply.
- the actuator includes a lamp connection means which is only activated if the supply voltage is that of the mains.
- a triac is used which will only be primed if the voltage available on the input terminals 43 of the actuator is close to that of the sector and in any case much greater than that delivered by the energy storage means.
- a relay and a voltage comparator can also be used to perform this function.
