Latest Patents

Jehyung Cho's latest patents include a power supply device and method for controlling the same. The first patent describes a power supply device that features a rectifier circuit for rectifying an inputted alternating current power supply. It includes a capacitor circuit with two capacitors connected in series, which smooths the rectified alternating current. An inverter converts the output power of the capacitor circuit to a preset power. The device also incorporates a switch for selectively connecting a middle node of the capacitors and a sensor for detecting the size of the alternating current power. A controller manages the switch based on the power mode confirmed by the sensor's output.

The second patent also focuses on a power supply device and method for controlling the same. This device includes a first switch element that selectively provides an alternating current power source to an actuation device. A second switch element is used to provide the AC power source to the first switch element. A detection circuit confirms whether the first switch element is fully turned on by comparing the input and output power sources. Additionally, a sensor senses the size of the AC power source, while a controller selectively controls the operation of the second switch based on the sensed size and the confirmed state of the first switch element.
