Abstract
Official abstract text for this publication.
A power conversion device for driving a load, including a power conversion device main body configured to receive an input of a power supply voltage and to drive the load, and a brake circuit configured to protect the power conversion device main body from overvoltage applied thereto. The brake circuit includes a Zener diode that becomes conductive when the voltage applied to the power conversion device main body exceeds a predetermined value, to thereby suppress the voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A power conversion device for driving a load, comprising: a power conversion device main body configured to receive an input of a power supply voltage, and to drive the load; and a brake circuit configured to protect the power conversion device main body from overvoltage applied thereto, the brake circuit including a semiconductor switch circuit that, when conductive, forms a bypass current path with respect to the power conversion device main body, thus…
