A contactless way to prolong the life-time of lighting applications by PWM (pulse width modulation) device power system is developed in this article. The system can match most sustainable energy, such as solar energy or wind power generator. It can automatically switch with the best way to control sustainable energy power system which fit in. On the other hand, because single chip can transfer power instantly to drive device up, like charge smartphone, it is a highly customize device. With the control system, traditional sustainable energy device can work much longer life-time and stable. Through adjustable wireless protocol, PWM, low-power multi-purpose regulator circuit and instant feedback display, so it can be optimized most sustainable energy devices. The proposed control system is built by a single chip microcontroller which is serving as the integration of the control core of the circuit, voltage feedback monitor at the same time. In order to improve system performance, the research made for different drive designs to analyze and compare, and simulated calculation and experimented.
