Title: Innovations of Jeong Nam Lee
Introduction
Jeong Nam Lee is a notable inventor based in Gyunggi-do, South Korea. He has made significant contributions to the field of power supply systems, holding a total of 6 patents. His work focuses on enhancing the efficiency and functionality of power supply devices.
Latest Patents
One of his latest patents is a power supply device designed to supply standby voltage using the main voltage. This innovative device includes a standby power unit that converts direct current (DC) voltage to an operating voltage, providing a first standby voltage to a standby output terminal. Additionally, a DC/DC converting unit receives the operating voltage and converts the DC voltage to a main voltage for the main output terminal. The main/standby power unit further converts the main voltage to a second standby voltage, which is also provided to the standby output terminal. Notably, the standby power unit adjusts the magnitude of the first standby voltage based on whether the second standby voltage is supplied.
Another significant patent involves an apparatus and method for controlling a power supply system. This apparatus includes an offset correction circuit that divides an input voltage into multiple segments and outputs divided voltages. A control unit utilizes an analog-to-digital converter (ADC) to detect these divided voltages and determines an offset correction value based on the differences between the detected voltages and the expected values.
