ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a multi-output mode charger, and more specifically to support different kinds of batteries for multi-model mobile telecommunication facility and provide different charging voltage and currents with a voltage and current regulating switch.
BACKGROUND OF THE INVENTION
Mobile telecommunication facility has become an indispensable part of our daily life that different kinds of its application are widespread used for indoor and outdoor activities, vehicles, and mountain areas. However, its durability and functionality are limited by its battery capacity. In fact the battery has-become a key point among those limitations.
Charging is a necessary process for mobile telecommunication facilities. For example, every family member has his own wired or non-wired equipments. However, batteries with different models and brands have different charging way of their own voltage and current requirements. This is one of the reasons that one is always not enough for a family usage. The result is a lot of money and resources wasted. In addition, these facilities can cause heavy contamination of our environment for their material can not be well decomposed.
To solve these problems, a multi-output mode charger is invented to support different kinds of batteries and power systems of different countries.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a multi-output mode charger which may support different kinds of voltage and current requirements. A voltage and current regulating switch which can provide different voltages and currents for different batteries of multi-model and brands in order to avoid the waste of resources and protect the environment.
The other object of the present invention is to provide a multi-output mode charger which employs a high-voltage end switch, a low-voltage end switch and a switch control circuit in its DC (direct current) power charge transformer section. That can reduce the weight and dimensions of the charger and makes this invention be portable.
The further object of the present invention is to provide a multi-output mode charger, which can support different kinds of charge connect set. Therefore, it can be applied to different kinds of batteries for multi-model and brands.
The further object of the present invention is to provide a multi-output mode charger which has a voltage transforming circuit and a current transforming circuit to sample the voltage and current output of the multi-output mode charger and feedback them to microprocessor. Those give more information for the microprocessor to refine the controlling on the multi-output mode charger, protect the batteries, and enforce the transforming efficiency.
Other features and advantages of the invention will become better understood from the following description of the invention which refers to the accompanying drawings.
