Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0021] According to the principle of inductive energy transfer technology, the present invention discloses a rotatable wireless power supply system for miniaturized radar, which mainly includes a separation transformer, a winding coil, a primary power supply circuit, and a secondary power receiving circuit. The power supply of the rotating module is up to 20W, and the power supply is stable during the rotation of the radar antenna, and the whole radar system works normally.

[0022] Such as figure 2 As shown, the separation transformer used in the present invention is a pot-shaped magnetic core, the primary magnetic core is fixed on the primary power supply circuit of the radar base, the secondary magnetic core is fixed on the secondary power receiving circuit on the turnt...

Abstract

The invention provides a small rotatable wireless power supply system which comprises a separating transformer, a power supply circuit and a power receiving circuit, the separating transformer adopts two tank-shaped magnetic cores of which openings are opposite, the tank-shaped magnetic cores serve as a primary magnetic core and a secondary magnetic core, and the center line of the tank-shaped magnetic cores is superposed to the rotating shaft of a radar rotating platform; the primary magnetic core is fixed to a radar pedestal, and the inner coil of the primary magnetic is connected with the power supply circuit; the secondary magnetic core is fixed to a rotary table, and the inner coil of the secondary magnetic core is connected with the power receiving circuit. According to the invention, a problem that a fixed radar pedestal supplies power to a radar function module rotating with an antenna is solved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of energy transmission, in particular to a wireless power supply system. Background technique [0002] Wireless power transmission technology refers to the method of transmitting electrical energy in a non-contact manner. It has a wide range of applications, and the transmission power varies greatly, ranging from tens of milliwatts for biological transplantation to tens of watts for small equipment, as large as Multi-kilowatt power for electric vehicles or mobile robots and multi-megawatt power for maglev train applications. [0003] Inductive Power Transfer technology (Inductive Power Transfer referred to as IPT) was first studied by Professor Bowles of the University of Auckland in New Zealand in the early 1990s. After more than ten years of hard work, this technology has achieved major breakthroughs in theory and practice. Power transformers are the most immediate application of this technology. The primary and s...
