Title: Step-up switching power supply device
Inventor: OTAKE TETSUSHI
IPC: H02M3/155
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To prevent burnout which occurs in a step-up switching power supply when a load is short-circuited or excessively applied.  <P>SOLUTION: When a load is short-circuited or excessively applied, a switch element is made to carry out a constant current function. Further, the switching of a main switching element is stopped by the timer latch function of a PWM controller. Thus, the switching power supply loses a boosting function, and an output is reduced down to input a voltage. As a result, the conduction of a switching element is stopped, and an input and an output are cut off from each other. In a normal operation, the switching element is brought into conduction, and a boosted voltage is obtained for the output.  <P>COPYRIGHT: (C)2004,JPO

Title: Small-energy boosting constant-discharge control device such as double-layered capacitor and secondary battery
Inventor: YAMAMOTO YOSHIO
IPC: H01M10/44
Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a circuit that outputs a constant voltage by boosting it by small energy using an output circuit formed of a double-layered capacitor and a secondary battery.  <P>SOLUTION: The voltage is raised by a boosting circuit formed of the capacitor and the secondary battery by small energy instead of being raised by connecting the capacitor and the battery in series. This arrangement dispenses with a space for the capacitor or the secondary battery for raising the voltage. In particular, the capacitor decreases the voltage from an initial voltage in a short time, and the voltage is stabilized at the level of 40% of the initial voltage, thus not allowing the initial voltage to be used as a working voltage (a voltage in designing the circuit). The maximum and minimum of the capacitor voltage developed by this new circuit are determined according to the operational condition of the boosting circuit. A discharge time is controlled by an inductance value. As a result, the voltage thus outputted is higher than the initial voltage, and the output of the constant voltage that does not drop with a lapse of time is obtained.  <P>COPYRIGHT: (C)2004,JPO
