Coupled- Inductor L- Source Inverter

Often this article anticipates a coupled inductor L-source inverter. When compared with the other existing inverters,it has an advantage of operating in 2 current modes, such as uninterrupted and discrete modes, since we use anancillary switch which is connected anti-parallel with diode in series with a capacitor to keep the DC voltageunchanged. But when compared to continuous conduction mode it works good in discontinuous conduction mode asit produce high voltage gain so thereby it reduces the Submissive component voltage stresses and lowers the coupledinductor values and power losses. This can be used for High Intensity Discharge Lamp application and for drivingBrush less DC motors. Topology of the circuit, strategy of modulation and operating principle are introduced. It isshown that mathematical formalism and observational results are verified
