sine wave inverter
Alternating current (AC) is electrical current that reverses its direction at a typical frequency of 60 Hz (cycles per second, or 50 Hz in South America and Europe). Conventional AC power is produced by rotating machines (alternators) that produce a smooth alternation, like that of a pendulum. it’s described mathematically as a “sine wave”. it’s the perfect waveform for the transfer of AC power.
An inverter is an device that converts DC to AC through a switching process. Thus it produces a kind of “synthesized” AC. There are two sorts of waveforms available from high-quality inverters. These are the so-called “modified sine wave” and therefore the “true sine wave”.
The “modified wave ” isn’t really a sine wave in the least . it’s a stepped wave, sort of a pendulum that’s being hit back and forth by soft hammers. It achieves voltage regulation by varying in breadth consistent with the battery voltage and therefore the load. Thus, the wave isn’t as smooth as a wave . the standard of “mod sine” inverters shouldn’t be underestimated, however. they’re highly capable, and (by narrowing the waveform) they save energy when running only small loads, as happens during most of the day during a typical home. They also cost half the worth of wave inverters!
True wave inverters are more efficient for running motors, including AC pumps. they’re less likely to draw complaints from people that enjoy top quality audio, or who simply have many electronic gadgets. If a mod-sine user features a problem with one or two small applications, here may be a solution. Add a second inverter to the system, alittle wave unit, to handle the matter circuits.
additional electrical noise could also be produced, exposure as a buzz in some audio equipment and from some transformers
some electric motors and transformers run hotter and draw a touch more power
digital clock and timing circuits are often fooled, sometimes counting double-time
in rare cases, power supplies in sensitive equipment are often damaged.
In spite of those occasional problems, mod-sine inverters are successful in many thousands of remote home, RV and marine systems since 1986.
