The Three-Carrier Quasi Switched Boost Inverter Control Technique

This paper presents a carrier modulation technique to control the three-phase, two-level quasi switched boost inverter. PWM algorithm uses three waves, first of which is for inverter while others are booster. The factor depends on short circuit interval DC/DC booster and When DC twice that inverter, index can be enlarged. new analyzed, calculated, simulated, tested. analysis calculation results show proposed reduce voltage link capacitor compared conventional approach. It reach 22.16% when ratio source effective reference 0.5. extend 29% under these conditions current ripple in inductor reduced by 4.8%. simulation experimental also similarities, thereby confirming calculation.
