Asymmetrical power converting apparatus employing self-arc-suppressing switches
The present invention provides a power converter system in which forward conversion capacities and reverse conversion capacities of semiconductor power converter apparatuses connected to a D.C. capacitor can be different from one another. The more suitable semiconductor power converter apparatuses can be selected in accordance with various loads. A power converter system includes semiconductor power converter apparatuses including a D.C. capacitor and power devices cooled by a cooling elements having an output terminal connected to a load. The semiconductor power converter apparatuses are connected in parallel with one another through the D.C. capacitor. Each of the power devices includes self-arc-suppressing semiconductor devices and diodes connected in anti-parallel with the self-arc-suppressing semiconductor devices. All of the semiconductor power converter apparatuses have the same circuit configuration. The power device of a first of the semiconductor power converter apparatuses has characteristics different from those of the power devices of the other semiconductor power converter apparatuses.
