This research proposed a phase inverter multi-voltage level has been developed as a five-level inverter voltage, three car shows the processing that has been created to work on a program.(THDV) least circuitry. This inverter signal PC double บลิวเอ็ม at 20 kilohertz Frequency Switching behavior that is part of the work of a switch with the inverseIt has a low-pass filter is a filter to keep out the high frequency output signal voltage and current wave form is a sign with a high-quality result, interference from electromagnetic attenuation.Advantages the inverter can also be five levels that will reduce the number of devices with the use of the switch. Switch helps to bring a two-way mixed with current drive signal switching.power loss due to the decrease in the current of switching and affect performance that will be used in the application.
