**6. Description of the inverter power supply**

The development of new useful energy sources is the key to continued industrial progress. Discovering new sources of energy, obtaining an essentially inexhaustible energy source, making it available everywhere and converting it from one form to another without polluting or destroying the environment are some of the great challenges in the world today. One of the techniques to tackle these challenges is to produce AC (Alternative Current) from DC (Direct Current) generated by fuel cells or solar panels and such device is called an inverter power supply. An inverter power supply is a device which can convert DC to AC that can be used in various AC applications. Many topologies are considered to be candidates for the inverter design and there are many factors affecting the choice of such topology, such as the size and the required efficiency as well as the cost of the inverter. In this study, an inverter power supply configuration is broken into two stages. The first stage is to step up the DC voltage level by using DC/DC converter and the second stage is to invert DC to AC through a DC/AC inverter. The block diagram of the inverter power supply is shown in Figure 4.

In this application, the operation of the electric circuit is controlled by the embedded system that includes the SH microprocessor and the embedded software. Development of the embedded software faces many challenges when using the traditional design method.
