Three-leg power converter apparatus
First Claim
1. A three-leg power converter apparatus, comprising:
- a first input/output port, a second input/output port, and a third input/output port with each of them having two terminals;
a three-leg bridge converter having three single-leg circuits, two DC terminals connecting with the two terminals of the first input/output port, and three mid-terminals, with each mid-terminal being located at a middle point of one of the three single-leg circuits;
a controller electrically connecting to the three-leg bridge converter for controlling an input or output current passing through each DC terminal and mid-terminal;
a filter circuit having one side connecting to two of the mid-terminals of the three-leg bridge converter and another side connecting to the two terminals of the second input/output port; and
a decoupling circuit having a first terminal and a second terminal respectively connecting to the two terminals of the second input/output port and a third terminal connecting to one of the two terminals of the third input/output port, with the other terminal of the third input/output port connecting to the other mid-terminal that dose not connect with the filter circuit.

Abstract
A three-leg power converter apparatus including first, second and third input/output ports, a three-leg bridge converter, a filter circuit, a decoupling circuit and a controller is presented. The three-leg bridge converter has three single-leg circuits, two DC terminals connecting to two terminals of the first input/output port, and three mid-terminals with each of them being formed by a middle point of one of the three single-leg circuits. The controller connects to the three-leg bridge converter for controlling an input or output current passing through each DC terminal and mid-terminal. The filter circuit connects between two of the mid-terminals and the second input/output port. The decoupling circuit has two terminals connecting to the second input/output port and another terminal connecting to a terminal of the third input/output port, with the third input/output port having another terminal connecting to the other mid-terminal that dose not connect with the filter circuit.
