Charging circuit based on generator for charging energy storage components

Abstract

The invention relates to a charging circuit for charging an energy storage component based on a generator, which comprises a generator converting mechanical energy into electrical energy, a rectifying circuit, a filtering circuit, a switching circuit, a charging manager and an energy storage component. A generator rotor and a mechanical component are connected through a transmission system to realize rotation, the generator rotor is provided with at least two sets of windings, and the windings form a series circuit and a parallel circuit. The charging manager detects the voltage value of the generating end or the direct current end of single set of winding, the rated charging voltage value of the energy storage component is used as a reference value of an alternating voltage, and the rated charging voltage value of the energy storage component is used as a reference value of a direct voltage. When an alternating current or a direct current is smaller than the reference value, the circuit is connected in series; when the alternating current or the direct current is larger than the reference value, the circuit is connected in parallel. After the circuit subjected to being connected in series or in parallel is rectified and filtered, the circuit charges the energy storage component after processed by a charging manager, the original dead voltage of the generating end becomes effective, generating resources are fully utilized, and the utilization ratio of the generator is increased.

Description

technical field [0001] The invention relates to a charging control circuit of an energy storage component, more precisely a charging circuit for charging the energy storage component based on a generator. Background technique [0002] Generators have a wide variety of applications. Small generators are often used in automotive power generation systems, portable machines, and emergency systems. Similarly, large generators provide power to large equipment, structures, and residential areas.

However, such loads are generally electrical equipment, but it is not disclosed whether it is applicable to energy storage equipment, and it is not disclosed whether this control system can be used for household appliances and other equipment

[0005] For the case where the energy storage device is used as the load, the voltage range that the current charging manager can handle to charge the energy storage component is the rated charging voltage value of the energy storage component Rated charging voltage value of energy storage components (For the voltage of the generator terminal), (if it is a DC terminal, it is "the rated charging voltage value of the energy storage component ~ m * The rated charging voltage value of the energy storage component"), the wide voltage range is m times (the charging voltage value is the best constant voltage value when charging the energy storage component with constant voltage, m is the current wide voltage range), not in The voltage value in this area cannot be handled

A lot of resources are wasted, and the utilization rate of generators to charge energy storage components is low
