    摘要： DC/DC bridge for controlling a direct-current load (M1), which bridge is provided with controllable semiconductor switches (S11-S14, S21-S26) and with a control unit (BC1). The bridge comprises two bridge sections (B11, B12), at least the first bridge section (B11) of which is controlled with pulse-width modulation (PWM) to regulate the current magnitude, and which bridge comprises a determination of the current of the direct-current load (M1). The second bridge section (B12) conducts direct current when the determined value (2) of the current of the direct-current load differs from zero by more than the limit value (1) of the current.

    摘要： The invention relates to an arrangement for protecting a component in a power supply circuit. The arrangement comprises determination of an electric quantity constituting a load on the component, which electric quantity constituting a load on the component is determined repeatedly while the component is exposed to the load. The arrangement also comprises estimation of instantaneous load capacity of the component, which estimation of instantaneous load capacity is performed using a limitation criterion set for the load capacity of the component. This limitation criterion indicates the longest possible operating time of the component under a given loading condition. For the limitation criterion, a representation with respect to the electric quantity constituting a load on the component is provided, and a limitation criterion corresponding to the defined electric quantity constituting a load on the component is derived repeatedly from the said representation while the component is exposed to the load. The estimate of instantaneous load capacity of the component is thus determined on the basis of both the limitation criterion defined substantially at the estimation instant and the limitation criteria defined before this.
