A transient voltage compensation apparatus and a power supply using the same are provided. The power supply mainly uses a compensation circuit coupled between an input terminal and an output terminal of a power converter. When a load of the power supply is switched in a very short time, a power coupled to the compensation circuit is retrieved to compensate the output of the power supply, such that the output voltage is kept steady, and the transient response of the power supply is increased.

A detent apparatus for water temperature regulation of induction faucets includes a mixer located in a faucet and a swiveling mechanism located in the mixer. The swiveling mechanism has a rotary valve and a handle located outside the mixer and the faucet. The handle is fastened to an end seat located on one end of the rotary valve through a coupling member. The detent apparatus includes a detent portion preferably formed integrally with the mixer and located on the outer surface of the mixer body in a protrusive manner. The detent portion has a top end surface spaced beneath a bucking portion of the end seat at a selected distance. When the end seat is swiveled the bucking portion hits a left bucking angle or a right bucking angle of the top end surface thereby the swiveling angle of the end seat is confined within a limited range.

A voltage regulator circuit with over-current protection, which includes a linear regulator, a voltage controller, and an over-current protection circuit. The linear regulator includes a converter and a driver. The converter is connected to a voltage input terminal and a voltage output terminal. An output terminal of the driver is connected to the converter for controlling the operation of the converter. The voltage controller is connected to the voltage output terminal, the output terminal and a first input terminal of the driver, respectively, for providing a feedback voltage. The over-current protection circuit is connected to the output terminal of the driver and the linear regulator. The over-current protection circuit detects the output voltage of the driver for comparing with a comparison voltage. When the output voltage is larger than the comparison voltage, the over-current protection circuit controls the driver to turn off the converter.

摘要:
A boost converter includes a first boost conversion unit and a second boost conversion unit. Coils of the first boost conversion unit and the second boost conversion unit are coupled with each other. Due to coupling of the coils, the second boost conversion unit releases energy while the first boost conversion unit stores energy in a period of time. Furthermore, due to coupling of the coils, the first boost conversion unit releases energy while the second boost conversion unit stores energy in another period of time. The two boost conversion units operate alternately, thereby adjusting switching loss and averaging output power of components. Furthermore, as switching frequency increases, the coil inductance, as well as the capacitance required in the two boost conversion units can be reduced correspondingly, thus substantially enhancing responses of the two boost conversion units as a whole.
