Paper Details

DC-AC inverters are electronic devices used to produce mains voltage AC power from low voltage DCenergy (from a battery or solar panel). This makes them very suitable for when you need to use AC power tools orappliances but the usual AC mains power is not available. Examples include operating appliances in caravans andmobile homes, and also running audio, video and computing equipment in remote areas. Most inverters do their job byperforming two main functions: first they convert the incoming DC into AC, and then they step up the resulting AC tomains voltage level using a transformer. And the goal of the designer is to have the inverter perform these functions asefficiently as possible. So that as much as possible of the energy drawn from the battery or solar panel is converted intomains voltage AC, and as little as possible is wasted as heat. One of the key factors pertaining to AC inverters is outputregulation. We take for granted the fact that our mains power is very well regulated. So you can plug almost anyappliance into a standard point outlet, and it will operate correctly. That’s because the electricity supplier has enormousgenerating plants, with automatic regulation systems to keep the mains voltage and frequency very close to constant,despite load variations of many megawatts. Inevitably you can’t get this kind of performance from a much smallerelectronic inverter, connected to a modest battery or solar panel as the energy source. However most modern inverterscan provide reasonably good regulation for loads of up to their rated capacity (given in watts) assuming of course thatthey are running from a well-charged battery.In this paper a brief review of most widely used methods for voltage regulation in AC inverters is explain and amutual comparison is also drawn.
