| Summary: | This master report presents a simulation voltage source control system for three
phase inverter focusing on reducing the common mode voltage using diode clamped
circuit. The model was implemented using MATLAB-Simulink with the
SimPowerSystems Block set and also M-file. The twelve Insulated Gate Bipolar
Transistor (IGBTs) was use as a switching device. In the three phase inverter circuit,
an Alternating Current (AC) output is synthesized from a Direct Current (DC) input
by closing and opening the switches in correct sequence or switching system. The
Pulse Width Modulation (PWM) is a program in M-file to control the ON/OFF
switching scheme of the IGBTs. An output voltage of an inverter with diode clamped
before load and after load will be monitored, discussed and compared to the basic
three phase inverter. This inverter circuit operate in open loop system where the
inverter output and the load in series connection. The effectiveness of the method
will be compared with the basic three phase inverter simulation model in MATLAB�Simulink program. |
