Power supply device with current multiplication

Abstract

Abstract This device is intended to be linked to a current source and to supply a load (ZL), at a voltage lower than that of the source, with a rectified current of mean strength higher than the mean strength of the current picked up from the source. According to the invention, the device comprises at least one output capacitor (CS) mounted in parallel at the terminals of the said load, at least one intermediate capacitor (CI) intended temporarily to store a charge (Q) and mounted in series with the capacitor (CS) in a circuit, called charge circuit, intended to charge the capacitor (CS) and the capacitor (CI), at least one transfer circuit controlled by switching means and linking the terminals of the intermediate capacitor (CI) to the terminals of the output capacitor (CS) in such a way as to transfer the charge (Q) to the capacitor (CS), and means (D2, D3) for inhibiting interactions between the charging circuit and the transfer circuit. <IMAGE>
