Analysis of SBI (Switched Boost Inverter) Based On Nano Grid Applications Using PWM Technique

Abstract

In order to supply power from a solar panel or photo voltaic system at a low voltage to a grid at high voltage, a power electronic converter which is capable of voltage boosting and inversion is required. Newly introduced Switched Boost Inverter is capable of achieving both these objectives by a single stage. This paper presents a PWM control strategy based switched Boost Inverter (SBI) for DC nanogrid applications. Using Switched boost inverter (SBI), the system can produce an ac output voltage which is either greater or less than that of the dc input voltage. This also exhibits better Electro Magnetic Interference (EMI) noise immunity as compared to the VSI, which enables compact design of the power converter. It allows the shoot through switching state for boosting the input voltage and, compensates the dead time effect which causes the serious output voltage waveform distortion and avoids the risk of damaging the inverter switches. It can supply both ac and dc loads simultaneously from a single dc input source. These features cannot be obtained in the traditional inverters and they are more advantageous for DC nanogrid applications. The whole system is designed, modeled and, simulated in a MATLAB software.
