Publication number: 20110149606Abstract: The AC power generated by AC utility has been successfully transferred from AC-to-DC by means of an AC-to-DC converting circuit. This disclosure provides an AC-to-DC converting circuit applicable to a power-charging module, and the AC-to-DC converting circuit comprises two parts such as a first stage being a low-frequency AC to high-frequency AC converter comprising an input full-bridge rectifier, a full-bridge inverter and an immittance conversion circuit and a second stage being an AC-to-DC converter comprising a single-phase transformer and a full-bridge rectifier, where the inverter in the first stage is switched at high frequencies so as to reduce the size of the transformer in the second stage. Additionally, the immittance conversion circuit is further characterized in voltage to current conversion so as to simplify the control mechanism of the power-charging module, reduce the number of current measuring elements and the cost thereof.Type: ApplicationFiled: March 26, 2010Publication date: June 23, 2011Applicant: Industrial Technology Research InstituteInventors: YEH-HSIANG HO, Yoshihiro Konishi, Yi-Shuo Huang

Patent number: 7612530Abstract: This present invention provides a bridge battery voltage equalizer to equalize the voltages of the serially connected battery strings, comprising at least one battery crossing over an energy-transferring circuit. A plurality of the energy-transferring circuits are interconnected in a bridge architecture. Each energy-transferring circuit having four nodes comprises a first semiconductor switch, a first diode, a second semiconductor switch, a second diode, and an inductor. One end of the first element switch is connected to a negative pole of the first diode thereto. A positive pole of the second diode is connected to one end of the second element switch thereto. The inductor is an energy storing element that crosses over between the negative pole of the first diode and the positive pole of the second diode.Type: GrantFiled: November 21, 2006Date of Patent: November 3, 2009Assignee: Industrial Technology Research InstituteInventors: Yoshihiro Konishi, Tain-Syh Luor, Yi-Shuo Huang

Patent number: 7049791Abstract: A battery energy balance circuit and a battery charging bypass circuit is disclosed for batteries being charged at the same time to be charged equally. When the terminal voltages of the batteries are different, a controllable power device switch in the circuit switches on and off at a high frequency in order to reduce the input current to the batteries with higher terminal voltages and to increase the input current to the batteries with lower terminal voltages, achieving the goal of equal charging. The disclosed energy balance circuit can avoid damages to the batteries as a result of overcharging. When the number of batteries increases, one can expand the system in a modularized way to prevent inconvenience of circuit designs.Type: GrantFiled: November 24, 2003Date of Patent: May 23, 2006Assignee: Industrial Technology Research InstituteInventors: Pao-Chuan Lin, Chun-Hsien Lee, Yi-Shuo Huang, Chung-Lin Lee
