Abstract

In un convertitore abbassatore di tensione a magnetica integrata incorporante un primo commutatore statico (Q1) controllato in frequenza è previsto, in serie a tale commutatore, un secondo commutatore statico di caratteristiche diverse (Q2) ed un circuito di pilotaggio (che può essere in forma integrato o a componenti discreti), il quale circuito, nel transitorio di accensione del convertitore abbassatore, mantiene il primo commutatore statico chiuso (Q1) mentre il secondo (Q2) viene commutato frequenzialmente in apertura e chiusura, mentre, raggiunte le condizioni di regime permanente il secondo commutatore (Q2) viene mantenuto sempre chiuso, ed il primo commutatore (Q1) viene frequenzialmente commutato in apertura e chiusura.In a built-in magnetic voltage-lowering converter incorporating a first frequency-controlled static switch (Q1), a second static switch of different characteristics (Q2) and a pilot circuit (which can be in form) are provided in series with this switch. integrated or discrete components), which circuit, in the ignition transient of the lowering converter, keeps the first static switch closed (Q1) while the second (Q2) is frequently switched in opening and closing, while, when the steady state conditions are reached, the second switch (Q2) is always kept closed, and the first switch (Q1) is frequently switched to open and close.
