converter regulator device voltage switching DC-DC, broad interval dt input modes and lifting reduction

摘要

converter regulator device switching DC-DC voltage low cost for suministrarpotencia to various components in an application automobile, comprising a terminal entradade excitation receives a drive voltage and which supplies first elements (22, 26) deconmutador in series, of which an outlet (24) intermediate feed means (40) of inductor, alimentandodichos means inductor to a terminal (36) output power, said deinductor means being connected through an intermediate tap of second elements (30, 32) switch in series losque a socket (36) terminal is an output terminal of said converter, a source of paracontrolar clock said elements (22, 26, 30, 32) switch the first and second being characterized said regulating device converter because the clock source is adaptadapara control said elements (22, 26, 30, 32) first and second switch by contro l latensión excitation below a first threshold voltage which provides a current salidadespreciable in a reduction mode by controlling the excitation voltage above unasegunda threshold voltage that provides a level plane mode current reduction alternating yoponiendo each other driving states of said first elements (22, 26) switch, and unmodo elevation by controlling the excitation voltage between these thresholds first and segundoque provides a level plane mode current elevation which is substantially less than dichonivel mode power reduction by excitation through said means for inducing dedicha intermediate tap of said second elements (30, 32) of series switch, and also estandocaracterizado that the means (40) inductor are external.
