Mohaiminul Islam 2 Introduction • Sinusoidal pulse width modulation (SPWM) is widely used in power electronics to digitize the power so that a sequence of voltage pulses can be generated by the on and off of the power switches. • The proposed alternative approach is to replace the conventional method with the use of microcontroller. The use of PIC18F4431 microcontroller brings the flexibility to change the real-time control algorithms without further changes in hardware. It is also low cost and has a small size of control circuit for the single phase full bridge inverter. The microcontroller has the built in dead time control circuit.

- 13. IUB S. M. Mohaiminul Islam 13 Conclusions In a single phase PWM signal has been implemented in PIC18F4431 microcontroller and gate driver’s IC IR2110 was used. Several outstanding features of the developed Sinusoidal PWM signal are highlighted as follows: • By generating the Sinusoidal single phase PWM signal have less harmonic; •both PWM signal and Dead time control circuits can be implemented in a single board microcontroller, which makes the system reliable, compact and low cost; •IR2110 IC can take two signals; one is used for independent signal and another is used for inverting signal. That means IC can also reduce the cost, compact and system reliable.
