摘要：In this paper, a novel single-phase 7 level inverter is proposed using coupled inductors. This inverter canoutput seven level voltages with only one DC source. Multilevel inverters with coupled inductors need only one sourcewithout input capacitors. For the inverter with coupled inductor, three limbs coupled inductors is the most desirableone; however, coupled inductor with high inductance value is not preferred. PWM control technique at 15 KHzswitching frequency is generated using TMS320F28069 DSP controller. Simulation is carried out for a 5 KVA singlephase inverter to check for 7 level output voltage and filter consideration in order to generate sine wave.12 switches arerequired to generate 7-level output. Finally, a prototype of 7-level inverter with 400 V input and 230 Vrms/5KW outputis implemented.
