Abstract

The invention discloses a light portable computer charging circuit. The light portable computer charging circuit includes a control system and a modulation circuit forming a USB interface in the control system, wherein the control system includes a quick charging power supply, the modulation circuit of the USB interface and electric equipment of different specifications. Larger mobile devices suchas notebook computers can be charged by adding the modulation circuit to a mobile phone quick charging device which is portable and mature and has high compatibility with mains supply, the portability and compatibility of a quick charger are used, a usual bulky laptop charger is replaced, the convenience of charging mobile devices such as notebook computers is improved, the improvement of the portability and endurance of the mobile devices is facilitated, power supply in different voltage areas, on-board, mobile power blank and other ways can be achieved, the voltage is transformed through aswitching circuit and a high-frequency transformer, and the portable and multi-compatibility charging method in which the current after voltage transformation is supplied to the electrical equipment by the modulation circuit is achieved.

Description

Technical field [0001] The invention relates to the technical field of electronic circuit products, in particular to a lightweight portable computer charging circuit. Background technique [0002] With the development of society, laptops, netbooks, and tablet computers are all developing in the direction of powerful functions and weight reduction. However, the supporting charger basically converts 220V alternating current into constant voltage direct current through the principle of inductance transformer and rectifier bridge to charge the electric equipment. The principle of inductance must use an inductance coil, which makes it difficult to reduce the size and weight of the charger. Moreover, the charger can only adapt to 220V city power, which is not suitable for use in vehicles, abroad, and mobile office. Many laptops, netbooks, tablet computers and other devices on the market are made very light, but device chargers are difficult to be as lightweight as fast chargers for m...
