Latest Patents

Joo-Dong Yu's two recent patents showcase his expertise in two vital areas of electronics. The first patent, titled "Low Power Dissipation Power Supply and Controller," describes an exemplary power supply design that minimizes power consumption in standby mode. This invention utilizes a startup circuit disabled by an under-voltage lockout signal, with variable frequency operation that is independent of feedback signals. The innovative standby mode detection circuit automatically activates variable frequency operation while ensuring that the startup circuit remains inactive to achieve negligible power dissipation. Additionally, his design employs a voltage-controlled oscillator that adjusts its frequency according to the rectified DC line voltage, effectively decreasing output power when line voltage increases.

The second patent addresses the advancement of capacitors, specifically through "High Dielectric Constant Embedded Capacitors." In this invention, Joo-Dong Yu introduces high dielectric constant capacitors made from lead-magnesium-niobate and lead oxide powders, mixed into dielectric inks. These inks can coat multiple glass-based green tapes, forming buried capacitors that are interconnected with conductive layers, such as silver. This innovative approach enables the development of multilayer capacitors with significantly high dielectric constants, eliminating the necessity for larger single-layer capacitors.
