Small portable non-contact charger for electronic facilities

The charging set includes base, rectification filter circuit of input voltage at primary side, pulse generating circuit, separate type transformer, rectification filtering circuit of transformer at secondary side. The end at secondary side of separate type transformer is connected to input end of rectification filtering circuit of transformer at secondary side. Output end of the rectification filtering circuit of transformer at secondary side through charging circuit is connected to rechargeable battery. The separate type transformer is composed of primary and secondary part independent from each other. The set includes two parts: charging base seat, and charging treatment set. Electrical energy is transferred between the said two parts through alternating electromagnetic field coupled by using separate type switching transformer. Features are: no any electric contact needed, reliable and favorable shape.
