OPEN LOOP POWER CONVERSION APPARATUS

摘要

An open loop power conversion apparatus is applied to a load apparatus and an input power. The open loop power conversion apparatus outputs a predetermined voltage to the load apparatus. The open loop power conversion apparatus includes a resonant inductor, a magnetic inductor, a resonant capacitor, and a transformer. The resonant inductor has a non-uniform air gap. An inductance of the resonant inductor is decreasing when a current outputted from the open loop power conversion apparatus to the load apparatus is increasing. An output voltage gain of the open loop power conversion apparatus is increasing, so that the predetermined voltage is increasing.
