Title: Teerasak Lee: Innovator in Wireless Power Technology
Introduction
Teerasak Lee is a prominent inventor based in Singapore, known for his contributions to the field of wireless power technology. With a total of eight patents to his name, he has made significant advancements in hardware and methods for voltage and current sensing.
Latest Patents
One of his latest patents is focused on hardware and methods for voltage and current sensing. This invention discloses a wireless power reception system that utilizes a switched capacitor DC-DC voltage converter to charge a load. The current sensing circuits described enable the measurement of the input current to the switched capacitor DC-DC voltage converter while being relatively insensitive to temperature variation. Additionally, the voltage/current sensing circuits allow for the selective measurement of load voltage, high side load current, and low side load current. Notably, one of the current sensing circuits can be used together with one of the voltage/current sensing circuits in a single device, or they may be used separately in different devices.
Another significant patent involves a foreign objection detection sensing circuit for wireless power transmission systems. This wireless power circuit operates in both transceiver mode and Q-factor measurement mode. It includes a bridge rectifier with inputs coupled to a coil and an output connected to a rectified node. The excitation circuit drives the coil with a pulsed signal during Q-factor measurement mode. A protection circuit manages the connection of the first terminal to a node based on the operational mode. The controller facilitates the bridge rectifier's function during Q-factor measurement mode, while a sensing circuit amplifies voltage to produce an output voltage, which is then digitized for Q-factor calculation.
