The Design of a DC/AC Inverter with the MC68HC11 Microcomputer

lectrical sources of low voltage levels (such as fuel cells, solar cells, storage batteries) are used in electrical space and terrestrial systems as power sources. The discrete low-level voltage sources are connected in series to obtain the desired voltage level. Some of these systems incorporate DC/AC inverters to handle their AC load. The sinusoidal waveshape output of the inverter can be produced in a conventional manner, i.e., by converting the total DC input to total AC output voltage. A different scheme (see Figure 1) was proposed I in which the sinewave was synthesized by the voltage sources
