The Best Cheapest 220v 12v 24v modified sine wave inverter modified sine wave for tv
modified sine wave inverter how about it? At this stage, most inverters on the market are dominated by modified wave inverters. The modified wave is suitable for most small-output household appliances and has a reasonable price, which is easy to be accepted by the sales market. This modified sine wave inverter can be used in notebooks, TVs, combined speakers, surveillance cameras, digital cameras, photocopiers, various charging heads, handheld computers, amusement equipment rentals, VCRs, China Mobile; home therapy devices, etc. , Inverters with high power can be used in small and medium electric water appliances such as hair dryers, electric cups, and kitchen appliances.
But for inductive load household appliances such as household refrigerators, hand drills, etc., it is not suitable for long-term application of modified sine wave inverter power supply system. Otherwise, it will cause damage to the inverter and related home appliances or reduce the estimated service life. Because of this kind of inductive load, household appliances have relatively high requirements on the wave type of current output. If an inductive load must be used, it is recommended to use a quasi-sine wave inverter with a large reserve output power. For example, a household refrigerator with a 150W inductive load must use a modified wave inverter of about 3000 watts.
Advantages and disadvantages of modified sine wave inverter
To
The sine waveform is relative to the sine waveform. Nowadays, the output waveform of the popular inverter is the modified sine waveform. The wave type of the inverter is divided into two major categories, the category is the sine wave inverter (that is, the pure sine wave inverter), and the other is the square wave inverter. The sine wave inverter outputs the same or even stronger sine wave AC current as the power grid that people usually use, because it can't find the electromagnetic pollution in the power grid.
To
The difference between the authentic wave and the modified wave of the inverter depends on:
To
1. The inverter method is different. Authentic wave inverters usually use the PWM method for inverter, and some even add multi-step inverters, which are cumbersome in structure, but have good output waveforms and are suitable for rational and capacitive loads. Modified sine wave inverters usually use the square wave method to invert, and very few add stepped inverters. The structure is simple, but the output waveform is poor, which is not suitable for rational and capacitive loads.
To
2. The output filtering method is different. The authentic wave inverter usually uses the LC filter method to obtain a more authentic sine wave. Modified wave inverters usually have a single-pole LC filter, and the output is similar to a trapezoidal wave.
Application field
1. Power frequency AC (ac) off-grid power generation system.
Household: TVs, computers, audio equipment, washing machines, electric lights, rice cookers, refrigerators, fans, air conditioners and other household appliances.
