Electronic or electrical components must have some source like a single phase. Running three-phase is only possible with single to three-phase inverted supply. To drive three-phase induction motor we use three-phase supplies. 2 Block diagram Figure 1 1 of single to three-phase supply consists of an input rectifier circuit filters inverter circuit load motor driving methodologies Arduino and output power supply. 7 From the above block diagram 1 1the one input is given to the rectifier and converter and the other is given to drive driver of IGBTs. Firstly the input rectifier from ac to pulsating dc. Therefore to remove that filters are used consists of resistors and capacitors which helps to terminate the ac and gives pure dc. Further supply is given to the inverter circuits IGBT’s are connected there. Now with ac power supply then energized block which is used for energizing IGBT s i e. DRIVING Block of Arduino where programs is run accordingly. Then converted dc is given to the inverter circuit to convert it into three-phase. 3 Then converted three-phase supply is given to the load which is induction motor of this project proved to convert a phase supply into three-phase power supply 10 As load may be induction motor or any other three-phase load but in the project, we use three-phase lamps two 100W lamps in each phase working in a good condition.

The Single to Three phase converter using IGBT’s for running three phase induction motor at 8 KHz switching frequency. By changing the frequencies the result was smooth like in increase and decrease of three phase induction motor. 9 The 220V AC supply is rectified using the bridge diodes and then it is converted to 3 phase supply. 6 The gate signal circuit is interface between the switching pulses of arduino as wave generator and the IGBT’s in this circuit. The arduino gives a 5Vsignals while the wave generated allow for a given voltage level. Further the IGBT’s here is not connected to ground then actual voltages have to drive IGBT’s gate depends on the voltage variation at emitter terminal. 1 Switching Signals currently have small drive systems a costly and gives control at high switching frequencies. 8 WORKING By above figure 1 1 the single phase 220V AC supply at the input and then rectifier circuit is connected that converts single phase AC to DC.

The filter capacitors are used to reduce the harmonics of the ac and gives the pulsating DC the fuse is connected for protection of circuits and resistors are used to limit current and then the converter circuit, is which the six IGBT switching device is to convert DC to three phase. AC Each IGBT gate is connected to every terminal of arduino pin. In arduino the avr microcontroller c program is installed and which drives the IGBT. We are giving 220v supply to rectifier for positive pulse three diodes are conducting and for negative two diodes are triggered and AC supply is converted into DC. In inverting block we used six IGBT as inverter. Upper side three IGBT are called as positive group. IGBT and lower side three IGBT are called as negative group IGBT 4 IGBT work in 180 degree mode of working operation in which one IGBT from upper group and another two from lower group and after that one from lower group another from upper group 3. Same procedure is followed by complete inverter circuit diode are connect across the each IGBT to limiting the reverse currents flowing through the inverters. At last three phase output is taken from middle of the two IGBT’s 8 Driver Circuit Without any traditional market available drivers we used the own logic and strategy to do this Firstly. 12 by 12 transformer is used to covert 220v to 12v then we convert it in dc by means of full wave rectifier circuit. Further we adjust voltage by LM317 by adjusting the value of R1 and R2 which gives 20v output Moreover two cascade bi junction polar transistors strategy is used to take output as a gate signal of igbt s as shown in the figure below.
