The author offers a power-efficient multichannel low-pass filter for digital image processing based on the cascade multiple accumulate finite impulse response (CMFIR) structure in this study. The CMFIR filter was created using the outputs of a linear time-invariant system (LTI), which was built using a cascaded integrator comb (CIC) and a MAC low-pass filter. The sample rate convertor based on CIC filters effectively conducts decimation or interpolation. The sample rate convertor with the CIC filter can only accommodate narrowband transmissions and so cannot be utilized for wideband signals. The MAC architecture-based sample rate convertor is a good solution for high-bandwidth signals, but it uses more resources like registers and flip-flops, which increases power consumption. Here, the CMFIR low-pass filter acts as an interpolator, introducing a sample to boost the image's resolution. CMFIR is a useful tool for addressing the issue of aliasing during sampling. In addition, the genetic algorithm was used to increase the filter's resource utilization and power consumption efficiency.

In recent years, single-phase Voltage Source Inverter (VSI) is extensively used in various applications such as single phase uninterruptible power supply for the residential consumers, single phase micro-grid single-phase rooftop solar energy conversion system and single-phase Vehicle to Grid (V2G) system. This paper concentrates on the development of single-phase VSI system controlled by suitable on-board microcontroller. Nowadays, dedicated real time controllers such as ACE 1103, 1104 controllers, MICROLAB box, PXI platform etc. are developed as a general purpose controller panel/board. These controllers are mainly used in the laboratory for real time testing, research and development activities. But, in the applications mentioned above, the system with dedicated controller is required. Therefore, the development of the above said power electronics system plays an important role in the field of electrical power industry[1]. The VSI generates harmonics in its output voltage. The harmonics generation should be limited to avoid poor load performances. Lower order harmonics mainly contributes to the distortion effects in the system. On the other hand, the higher order harmonics effect less distortion in the system. Therefore, high switching frequency pulse width modulation techniques such as Sine-Triangle Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) are commercially used to remove the distortion effect created by the lower order harmonics. In this case, system efficiency is reduced due to higher switching losses by adopting these high frequency Pulse Width Modulation (PWM) techniques. Therefore, lower switching frequency Selective Harmonic Elimination PWM (SHEPWM) technique is considered in this paper to get the double benefits of lower switching losses and the removal of lower order selective harmonics.
