节能老化实验装置的一种电路

THE CIRCUIT OF SAVING ENERGY AGING EXPERIMENT EQUIPMENT

根据有源逆变原理，将ＵＰＳ设备老化负载由原电阻器换为有源逆变器，可将原发热浪费的能量转换成交流电能回馈到电网，获得再生利用，达到节能的目的，本文给出了老化节能负载装置的有关原理、电路结构和控制方法，可供用户开发成新的节能产品。

Based on the principles of active invert,the resistor used as the load ofUPS aging is substituted by active invert.By this way,the energy wasted by resistorbefore can be transformed into AC power fed back to network. So the energy canbe reused. The paper introduces the principles of this equipment,the circuit dia-gram and the controlling techniques.It enable users to develop thenew products of saving energy。
