Abstract

The invention relates to a magnetic field-based AC-to-DC rectification module, which comprises a magnetic core, a control unit and a load unit, and is characterized in that the magnetic core comprisesa first end surface and a second end surface which are oppositely arranged, and the control unit comprises a control coil, a control power supply, a control switch and a control resistor; wherein thecontrol coil, the control power supply, the control switch and the control resistor form a control loop, the load unit comprises a load coil, one end of the load coil is load input, the other end ofthe load coil is load output, and a load switch and a load resistor are further arranged between the load input and the load coil. The control coil and the load coil are respectively wound on the first end surface and the second end surface. The invention further discloses an AC-to-DC rectifying method based on the magnetic field. The characteristic that the magnetic field generated by the electrified coil and the magnetic saturation magnetic field of the magnetic core can be counteracted is used for achieving one-way passing of current, and the AC-to-DC rectification module is more suitable for strong current and high power use scenes. And the AC-to-DC rectification module is also suitable for a weak electric signal control domain.

Description

technical field [0001] The invention relates to a power conversion method, in particular to a magnetic field-based AC-to-DC rectification module and method. Background technique [0002] Existing rectification methods basically use semiconductor devices such as diodes. Using the unidirectional conduction characteristics of semiconductor diodes, four diodes are integrated into a rectifier bridge to achieve AC to DC conversion. They are all semiconductor devices. Semiconductor devices are very suitable for low-power and low-power electrical signal processing. However, when using high-power electrical equipment, breakdown and failure are prone to occur. Contents of the invention [0003] Based on this, it is necessary to provide a magnetic field-based AC-to-DC rectification module and method for the problem that high-power electrical equipment is prone to breakdown and failure during sorting. [0004] A rectification module based on a magnetic field from AC to DC, characteri...
