Abstract

The invention discloses an overflow energy storage type power supply circuit, comprising an energy storage circuit, a rectification filter circuit, a boost circuit, an overvoltage detection circuit, an overcurrent detection circuit, a first switch control circuit S1 and a second switch control circuit. In the working process of a micro-generator based on an elastic energy storage element, the rotating speed of the generator is gradually decreased from high rotating speed to low rotating speed. During normal work, under the control of an overvoltage detection circuit, the energy storage type circuit stores redundant electric energy in a previous stage with a higher rotating speed, and releases the stored electric energy through the boost circuit in a later stage with a lower rotating speed;and when overload occurs, under the control of the overcurrent detection circuit, the energy storage type circuit stores electric energy generated by the generator for subsequent use. According to the invention, the power supply time of the micro-generator based on the elastic energy storage element is prolonged, and the overall efficiency of the generator is improved.

Description

technical field [0001] The invention belongs to the field of micro generators, and in particular relates to an overflow energy storage type power supply circuit. Background technique [0002] In some portable devices with long-term storage requirements, in order to ensure that the supporting power supply does not fail within the storage period, physical power sources based on micro-generators are often used instead of chemical power sources such as batteries. This type of micro-generator mainly uses elastic elements such as springs, coil springs or springs to store energy. These elements are tightened before storage. When the portable device needs power, the elastic potential energy stored in it is converted into electrical energy by releasing the elastic element. The support device is working properly. [0003] CN201710011983.2 discloses a "spring spring micro-generator", which stores energy on the spring spring by manpower rotating the knob, and then controls the slow rel...
