Abstract:
A synthesis method for improving terminal current properties of power conversion networks applicable to an original three terminal power conversion network having,a first power conversion network terminal a second power conversion network terminal for which terminal voltage of said second power conversion network terminal differs from terminal voltage of said first power conversion network terminal by a DC voltage, a third power conversion network terminal, a first winding network, having first and second terminals, connected in series with said third power conversion network terminal, said first wind network having a single winding or a combination of windings connected to each other in a series and/or parallel structure, comprising the steps of,(a) add a second winding network, having first and second terminals, of the same structure as said first winding network with said first terminal of said second winding network connected to said first power conversion network terminal, (b) add a third winding network, having first and second terminals, of the same structure as said first winding network with said first terminal of said third winding network connected to said second power conversion network terminal, (c) add a first capacitor, having first and second terminals, with said first terminal of said first capacitor connected to said first power conversion network terminal and with said second terminal of said first capacitor connected to said second power conversion network terminal, if said original three terminal power conversion network does not already comprise a capacitor connecting said first power conversion network terminal to said second power conversion network terminal, whereby a new three terminal power conversion network, defined by said third power conversion network terminal, said second terminal of said second winding network, and said second terminal of said third winding network, is formed with reduced terminal current ripple by comparison to said original three terminal power conversion network.
