摘要：Switched Boost Inverter (SBI) is a singlestage DC to AC power converter and it is derived fromthe Z - source inverter employs an LC impedancenetwork in between the main inverter bridge and thepower source. This SBI converter can possible to supplyboth DC and AC loads simultaneously from a single dcinput source. Here, reducing the inverter switchingstress. Also, this converter provides to shoot- through ofthe inverter legs without causing any damage to theinverter switches. The unique feature of the SBI, it canoperate either in buck or boost mode operations with awide range of obtainable output voltages from a giveninput voltage, unlike the traditional buck-type voltagesource inverter.SBI construct similar advantages ofconverter uses more switching devices and lowernumber of passive devices compared to the original ZSI.Along with its pulse width modulation (PWM) controlstrategies is give the inverter switching pulse. Thesefeatures make the SBI suitable for variable motor speeddrive application. The SBI reduce the electromagneticinterference noise immunity when compared to the VSI.which enables the compact design of the powerconverter.Here BLDC motor drive is using as a DCload and AC load as resistive load and non linearload.The theoretical and modulation concepts presentedhave been verified in simulation .The operating modesof the proposed converter are simulated usingMATLAB.
