Problems solved by technology
However, in this power supply scheme, a high-performance high-frequency power supply needs to be installed at each magnetic coupling coil on the road, resulting in high construction and maintenance costs for the power supply system; The coupling coefficient between the power supply coils cannot always be kept high, so the power supply efficiency is greatly affected; also for this reason, when the moving body is in motion, it is difficult to keep its power supply stable

Description
technical field [0001] The invention relates to new energy technology, in particular to providing a non-contact power supply system for electric or hybrid mobile bodies, and in particular to a cascaded non-contact power supply system and a mobile power receiver. Background technique [0002] The construction of a low-carbon society has created a great demand for electric vehicles such as high-speed trains and electric vehicles. At present, the electric mobile body mainly adopts: first, to realize the continuous power supply to the electric locomotive through the catenary; second, to use the storage battery to realize the staged power supply to the small electric vehicle. However, the power catenary has many lines, complex technology, high cost, and is prone to failure under severe weather conditions; excessive production of chemical storage batteries is also a potential threat to the natural environment. If the electric mobile body can be powered in a non-contact (or wirele...
