- They have a maximum output voltage limit, which is relatively low. For outputs of the order of hundreds or thousands of volts do not work;

- They have a minimum and maximum operating temperature due to the intrinsic characteristic of their electronic components. They can generate problems in very places

hidden areas in which ventilated boxes cannot be available, and whose maintenance is not possible.

Detailed description of the invention and presentation of a preferred embodiment of the invention

A preferred embodiment of the invention is described in detail, among the 5 different possible alternatives, by enumerating its components as well as its functional relationship, based on references to the figures.

Figure 1 (Fig.l) .- shows a schematic view of the tension booster device (1). The input terminal (100) can be seen, which serves to introduce the reduced input voltage 10 of the direct current type, the negative pole being applied to the input terminal (100a) and the positive pole to the input terminal (100b) ; The value of the input voltage has no restrictions but typical values can be millivolts. A plurality of primary capacitors can be observed (101: 101a, 101b, 101c, 101 d, lOle, lOlf, lOlg, lOlh, lOli), as well as a secondary capacitor (102). The primary capacitors are initially connected in parallel connection to be charged to the reduced input voltage, subsequently and by means of a plurality of contacts (1041, 1042, 1043) of a timed bi-stable relay (104), they are passed to a serial connection, the voltage being n-times high (where n is the number of capacitors); they are disconnected from the input (100) and connected to the secondary capacitor 2 0 (102) by charging the high voltage. There is an inverter (103) that is permanently powered by the secondary capacitor (102) and that generates alternating voltage at the output terminals (105), if it is desired that the high output voltage be of the direct current type dispenses with the investor (103); neutral at the output terminal (105a) and phase at the output terminal (105b). The bi-stable relay

Timed 2 5 performs an on-off charge-discharge cycle of the plurality of capacitors

primary (101). The on-off times are adjustable.

Figure 2 (Fig. 2) .- shows a partial schematic view of the voltage booster device (1), with detailed reference of the contacts (1041, 1042, 1043) of the relay

3 0 bi-stable timed (104). The pair of NC contacts bi-stable relay input (1041), are

contacts that in the initial state are normally closed. The plurality of NC contacts bi-stable relay series-parallel (1042), are also contacts that in the initial state are normally closed. The pair of NC contacts bi-stable relay output (1043), are contacts that in the initial state are normally open. The relay must be considered

3 5 being bi-stable has stable positions, but for clarity in the

Exposure assumes an initial position.

Figure 3 (Fig. 3) .- shows a partial schematic view of the booster device (1), with the position of the contacts (1041, 1042, 1043) indicated graphically

4 0 so that the plurality of the primary capacitors (101) are in parallel, and therefore

both in charging mode. The following graphic symbology has been used:

(-): closed contact, the passage of electric current is allowed;

(X): open contact, the passage of electric current is not allowed;

The figure shows that the plurality of primary capacitors (101) are in parallel connection and are being charged with the reduced input voltage.

Figure 4 (Fig. 4) .- shows a partial schematic view of the voltage booster device (1), with the position of the contacts (1041, 1042, 1043) indicated graphically so that the plurality of the primary capacitors (101) are in series, and therefore in download mode. The figure shows that the plurality of primary capacitors 5 (101) are in serial connection, are disconnected from the input voltage, and their output is closed so that they charge the secondary capacitor (102) with high voltage.

Figure 5 (Fig.5A, Fig.5B, Fig.5C) .- shows a schematic view of a primary capacitor 10 with polarity switch (101b, 101d, 101f, 101h). It is necessary to switch the polarity of the indicated capacitors when they are in series, and therefore in discharge mode. In Fig.5A one of these capacitors with polarity switch has been represented and it is distinguished from those without a switch because the symbol includes a circle. The position of the contacts of the switch (1042ab, 1042cd, 1042ef, 1042gh) is indicated in Fig.5B so that there is no polarity change. The position of the switch contacts (1042ab, 1042cd, 1042ef, 1042gh) is indicated in Fig.5C so that there is a polarity change.

The main feature of the invention is that it does not have any energy consumption of the input allowing its use in ultra low power conversions.
