Abstract
Provided is a power conversion circuit, including: a first switching element and a second switching element connected in parallel to each other; and a control unit configured to control turn-on/off of each of the switching elements, wherein a current value at a cross point of current-voltage characteristics when a forward current flows through the first switching element and current-voltage characteristics when a current flows through the second switching element is greater than a rated current value of the power conversion circuit.
Claims16
A power conversion circuit, comprising:
- a first switching element and a second switching element connected in parallel to each other;
- and
- a control unit configured to control turn-on/off of each of the first and second switching elements, wherein
- a current value at a point of intersection of a first curve, which represents current-voltage characteristics of the first switching element when a forward current flows through the first switching element, and a second curve, which represents current-voltage characteristics of the second switching element when a current flows through the second switching element, has a higher value than a rated current value of the power conversion circuit.
A power conversion circuit, at least comprising:
- a first switching element and a second switching element connected in parallel to each other;
- a control unit configured to control turn-on/off of each of the first and second switching elements;
- and
- a reactor connected in series to the second switching element,
- wherein inductance of the reactor is adjusted to a value causing a voltage applied to the first switching element when a predetermined short-circuit current is generated in the power conversion circuit not to exceed an allowable withstand voltage value of the first switching element.
