Abstract
An interference suppression stage for a power supply. The interference suppression stage has an input connected to an input module of the power supply, the input module connected to an electrical supply system, an output connected to an output module of the power supply, the output module connected to an electrical load, at least two power paths connected in parallel between input and output, wherein each of the power paths are configured to be switched between an active state and an inactive state, and a control unit configured to switch at least one of the power paths to the inactive state in a saving mode. The control unit switches different power paths alternately in time to inactive in saving mode.
Claims10
An interference suppression stage (12) for a power supply (2), the interference suppression stage (12) comprising:
- an input (14) connected to an input module (4) of the power supply (2), the input module (4) connected to an electrical supply system (6),
- an output (16) connected to an output module (8) of the power supply (2), the output module (8) connected to an electrical load (10),
- at least two power paths (18a-c) connected in parallel between input (14) and output (16), wherein each of the power paths (18a-c) are configured to be switched between an active state (A) and an inactive state (I),
- a control unit (20) configured to switch at least one of the power paths (18a-c) to the inactive state (I) in a saving mode (S),
- wherein the control unit (20) switches different power paths (18a-c) alternately in time to inactive (I) in saving mode (S).
