Method and arrangement in a DC-to-DC converter |
摘要 |
A method and an arrangement for controlling the output voltage (V2) of a DC-to-DC converter (100). The DC-to-DC converter (100) comprises converting means (101) and regulating means (102). The converting means is fed by a first DC-voltage (V1) from the regulating means. The first DC-voltage (V1) is determined by a feed back portion (VDIV) of the output voltage (V2) from the converting means and a reference voltage (VREF). The reference voltage is derived from a pulse train (PT1). The output voltage (V2) depends on both the first DC-voltage (V1) and the pulse train (PT1). The output voltage (V2) from the DC-to-DC converter is kept constant under varying load and the output voltage level can be adjusted in an easy and flexible manner by the pulse train. |
