Multilevel inverters have drawn increasing attention in recent years, especially in the distributed energy resources area. Several renewable energy sources (batteries, fuel cells, solar cells, wind turbines or micro turbines) can be easily connected through a multilevel inverter to feed a load (off-grid) or interconnect to the ac grid (grid-tie) without voltage balancing problems. Moreover, multilevel inverters have a lower switching frequency than standard PWM inverters and thus have reduced switching losses. The output waveforms of multilevel inverters are in a stepped form, resulting in reduced harmonics compared to a square-wave inverter. In the present work, PIC 16F877A microcontroller based triggering circuit has been designed to be used with various levels of multilevel inverter. Multiple pulses with relative delay and requirement of a single variable dc supply (0-5V) for the control of all delay angles, makes it cost effective and simple. In addition, PIC 16F877A are cheaper with respect to other 8 bits microcontrollers available in market. It is a RISC controller with only 25 instruction sets. The Harvard architecture makes it more attractive. The simulation is done using MPLAB IDE and PROTEUS 7. Practical circuit has been designed and successfully implemented.
