icon0 battery consumption As seen before, the best trick we can use to avoid wasting energy is to use an extreme low-current microcontroller that allows us to enter sleep mode. In our case, we have used a PIC18LF14K50, which has the XLP (Extreme Low-Power) capabilities from Microchip. Furthermore, By avoiding the use of LDOs is always a piece of good advice to save some extra energy. That's why we power our microcontroller directly from the CR2032, at a rated voltage of 3.3V.

When the PCB arrived from our great sponsor PCBWAY, the next step was to order all the components and solder them in the board to check if everything works as intended. Today we are gonna see all the processes from the PCB board to the final product. 

Icon0 inverter

To properly control an inverter, a modulation technique is needed. Many different approaches could be done to control it. Nevertheless, some parameters such as DC-link voltage utilization, produced harmonics and the final implementation with a DSP (Digital Signal Processor), should be considered before choosing which one is the most suitable for any project.
