Patents by Inventor Te-Yu Chou

Te-Yu Chou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Battery module, method for managing supply of electrical power by the battery module, and power supply device having the battery module
    Patent number: 9472952
    Abstract: A battery module includes a plurality of battery units, each of which supplies electrical power to a load through a respective linear regulator. In a method for managing supply of electrical power by the battery module, a number of battery units that supply electrical power to the load is controlled according to magnitude of a current required by the load, so as to reduce power loss in the linear regulators.
    Type: Grant

  • DC-based uninterruptible power system and method for detecting abnormal voltage
    Patent number: 9285434
    Abstract: A direct current (dc) uninterruptible power system is disclosed. The dc-based uninterruptible power system includes a multiplexer, a battery unit, a linear regulator, a switch-transistor, a voltage comparator and micro controller. The multiplexer receives a first control signal, a first reference voltage and a second reference voltage and outputs a control voltage according to the first control signal. The switch-transistor has a body diode and the body diode has a conduction voltage. When the dc-based uninterruptible power system is non-discharge mode, the switch-transistor is switched-off and the linear regulator receives the first reference voltage, so that the subtraction of the output voltage and the power-supply voltage is smaller than the conduction voltage to cutoff the body diode.
