TLDR
In this paper, a very high gain step up DC-DC converter of multilevel output voltage is proposed, which operates in continuous conduction mode and has high voltage gain.Abstract:
In this paper a very high gain step up DC-DC converter of multilevel output voltage is proposed. Maximum voltage gain in conventional Boost converter like, switched inductor converter, cascaded Boost converter, switched capacitor converter etc. are limited due to extreme duty cycle (i.e. duty cycle near to unity). Operation at extreme duty cycle leads to, serious reverse recovery problem at the switches, high conduction losses, high electromagnetic interference etc. Isolated converter such as fly-back converter, push-pull converter, forward converter, bridge converters etc. overcomes the above issues, where basically a transformer or coupled inductor is used to Boost the voltage. But, inclusion of transformer or coupled inductor introduces voltage spike at the main switch and power loss due to leakage inductance. Recently, DC micro-grid gets major importance because of the significant increase in DC loads and demand of high quality power. These DC loads require different voltage levels based on their power ratings. Photo voltaic source (PV) is one of the prime source of energy in DC micro-grid. A very high voltage gain converter is the need for DC micro-grid because of low PV source voltage. In this regard, here a step up DC-DC converter topology is proposed, which possess a very high voltage gain characteristic. The proposed converter operates in continuous conduction mode.read more
