Abstract
An electrical power supply system, in particular for a microgrid, includes a DC bus, and a first rectifier and a second rectifier, with the first and second rectifiers each supplying power to the DC bus. The first rectifier is a diode rectifier and the second rectifier has switchable power semiconductors. The electrical power supply system further includes a generator supplying power to both rectifiers. The rectifiers can be connected at different times according to a load.
Claims16
An electrical power supply system, comprising:
- a segmented DC bus including a plurality of segments, with two of the plurality of segments each include at least one feed;
- a first rectifier constructed as a diode rectifier, a second rectifier comprising switchable power semiconductors;
- and a generator designed to supply power to the first and second rectifiers for supply of power to the DC bus, wherein an output power the first rectifier is at least ⅓ of an output power of the second rectifier, and wherein the output power of the second rectifier is at least ⅓ of the output power of the first rectifier, and wherein the two segments supply different loads separately from one another.
A method for operating an electrical power supply system comprising a segmented DC bus which includes a plurality of segments, with at least two of the plurality of segments each including at least one feed, the method comprising:
- supplying power to the segmented DC bus from a first rectifier constructed as a diode rectifier and from a second rectifier comprising switchable power semiconductors, with the first rectifier having an output power which is at least ⅓ of an output power of the second rectifier;
- and the output power of the second rectifier being at least ⅓ of the output power of the first rectifier,
- switching the first and second rectifiers at different times depending on a connected load, and
- activating the feeds of the at least two segments depending on the connected load.
