Title:
A power converter and a method for controlling the same
Document Type and Number:
Japanese Patent JP6177858
Kind Code:
B2
Abstract:
A power conversion device includes a power supplying terminal, a switching converter, a signal injector, a coupler circuit, a detecting circuit and a controller. After an input voltage is converted into an output voltage by the switching converter, the output voltage is outputted to a load through the power supplying terminal. The signal injector provides a signal. When the load is connected with the power supplying terminal, an operating parameter at the first end of the coupler circuit has a first variation value in response to the signal. When the load is disconnected from the power supplying terminal, the operating parameter at the first end of the coupler circuit has a second variation value in response to the signal. According to the detecting result of the detecting circuit, a switching action of the switching element is selectively enabled or disabled by the controller.
