Title: Innovations by Seng-Pan U: Pioneering Wireless Power Transfer Technologies

Introduction

Seng-Pan U is a notable inventor based in Macau, CN, recognized for his contributions to the field of wireless power transfer. With a total of 14 patents to his name, he has made significant strides in developing technologies that enhance energy efficiency and convenience in mobile devices.

Latest Patents

One of his latest innovations is the "Reconfigurable Bidirectional Wireless Charging Transceiver." This invention addresses the urgent need for mobile devices running low on energy by providing a bidirectional wireless power transfer (WPT) solution. The transceiver is designed to be reconfigurable, allowing it to perform both WPT and wireless power reception (WPR) with minimal additional costs. By utilizing a maximum current charging mode (MCCM), it maximizes battery-to-battery (B2B) charging efficiency, reducing the number of cascaded charging stages from five to three compared to conventional designs.

Another significant patent is focused on "Limit Cycle Oscillation Reduction for Digital Low Dropout Regulators." This method effectively minimizes the limit cycle oscillation (LCO) amplitude of a digital low dropout regulator (D-LDO) by incorporating auxiliary unit power transistors in parallel with the main PMOS array. The improved D-LDO features an auxiliary power transistor array driven by a comparator output, which enhances performance by reducing LCO amplitude.
