Coupled- Inductor L- Source Inverter

Abstract

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 an
ancillary switch which is connected anti-parallel with diode in series with a capacitor to keep the DC voltage
unchanged. But when compared to continuous conduction mode it works good in discontinuous conduction mode as
it produce high voltage gain so thereby it reduces the Submissive component voltage stresses and lowers the coupled
inductor values and power losses. This can be used for High Intensity Discharge Lamp application and for driving
Brush less DC motors. Topology of the circuit, strategy of modulation and operating principle are introduced. It is
shown that mathematical formalism and observational results are verified
