Abstract
Un generatore di tensione stabilizzata comprende: un modulatore PWM; mezzi interruttori (19) pilotati da detto modulatore PWM tra un ingresso, a cui è applicata la tensione di alimentazione (Vi), ed un'uscita (29), a cui è collegato il carico; e mezzi per rilevare la variazione della tensione sull'uscita e per modificare il duty-cycle del modulatore PWM in modo da contrastare detta variazione; detti mezzi comprendono in combinazione: una rete (5) di controllo del duty-cycle del modulatore PWM (14), il segnale in uscita della quale è definito da F = A2 (sen2 v(t) + cos2 v(t))dove v(t) è una tensione proporzionale alla tensione di uscita del dispositivo; ed una rete di controreazione che applica all'ingresso del modulatore PWM un segnale di controreazione funzione della tensione di uscita del generatore.(Fig. 1).A stabilized voltage generator includes: a PWM modulator; switch means (19) driven by said PWM modulator between an input, to which the supply voltage (Vi) is applied, and an output (29), to which the load is connected; and means for detecting the variation of the voltage on the output and for modifying the duty cycle of the PWM modulator so as to counter said variation; said means comprise in combination: a duty cycle cycle network (5) of the PWM modulator (14), the output signal of which is defined by F = A2 (sen2 v (t) + cos2 v (t)) where v (t) is a voltage proportional to the output voltage of the device; and a feedback network that applies a feedback signal as a function of the generator output voltage to the input of the PWM modulator (Fig. 1).
