6 results about "Capacitive power supply" patented technology

A capacitive power supply, also called a capacitive dropper, is a type of power supply that uses the capacitive reactance of a capacitor to reduce the mains voltage to a lower voltage. There are two important limitations: First, the high withstanding voltage required of the capacitor, along with the high-capacitance required for a given output current, mean that this type of supply is only practical for low-power applications.

Energy-consuming valve power module cyclic aging test platform and test method

The invention discloses an energy-consuming valve power module cyclic aging test platform and a cyclic aging test method, which are suitable for reliability verification of a direct-current energy-consuming device power module. Through collaborative design of a capacitive power supply and an inductive load, closed-loop utilization of energy is realized, and modularized alternating test logic is adopted, so that the test efficiency is improved. A direct-current power supply is used for providing a current source for a test loop, a test object is a test valve section formed by connecting a plurality of power module units in series, the test loop is composed of two test valve sections, and the two test valve sections are tested objects mutually. The design of the series energy consumption valve power module enables a plurality of tested modules to be subjected to cyclic aging at the same time. According to the invention, the power circulation of the energy consumption branch can be realized, and the data obtained through the test can be applied to key scenes such as health condition evaluation and control logic judgment of the IGCT device.

Capacitive power supply enhancement

The present invention concerns a power supply arrangement for a portable electronic device. The inventive arrangement uses a large value capacitor in the power supply circuitry to extend the operational life of the battery. The large capacitor builds up the power reserve thereby increasing current output. Because of the small footprint of the device, multiple smaller capacitors are connected in series to build up the large capacitor value. The arrangement preserves battery power by reducing the leakage typically present when using a single large capacitor. The arrangement also effectively reduces the battery's internal resistance.
