Latest Patents

Vincent Liu holds a patent for a Switch-mode power supply. This invention discloses a Power Factor Correction Controller, which comprises a boost converter, a current sensing unit, an arithmetic unit, and a switch driving unit. The current sensing unit can sense or derive the current that passes through the energy delivery device, which is typically implemented by a diode or a switch. Additionally, the current sensing unit can sense the inductor current or the switch current. With this current sensing unit, the arithmetic unit can calculate the optimum switch on-time or determine when to turn off the switch, without the need for direct sensing of the load. This method reduces system costs by eliminating the need to sense load conditions, as seen in prior arts. Furthermore, it improves system response by sensing the delivered current at the energy delivery side, rather than the receiver side.
