A pure sine wave inverter is a type of inverter that converts DC power to the same smooth sinusoidal AC power as the National Grid. Inverters are divided into pure inverters and repair inverters.
① adapt to all electrical appliances power supply waveform, pure sine wave inverter is issued by the smooth curve and the national standard power is the same curve issued by the AC power can be used by all electrical appliances
② low noise, power saving, high efficiency, compared to repair the sine wave inverter pure sine wave inverter power generation in the same power inverter under the same amount of input DC pure sine wave inverter output power more, while used for fans and other resistive loads appliances using pure sine wave appliances smaller
③Protection of the inverter, protection of electrical appliances, repair the current image generated by the sine wave inverter is a square output in the use of inductive appliances can not be used, such as cell phones, if the use of repair the sine wave inverter will directly burn the battery and cell phone capacitance, only the pure sine wave can be used at random
Voltage stability, no electromagnetic interference, and the same repair sine wave inverter voltage compared to the pure sine wave inverter voltage stability, compared with the national grid pure sine wave inverter no battery interference, more pure than the national electricity, the national grid electromagnetic interference is completely does not affect the use.
The price is expensive, with the same power to repair the sine wave inverter pure inverter price to about 3 times more expensive.
Pure sine wave inverter using isolated coupling circuit, first of all, the inverter needs to come from the battery or solar panels and other equipment that can provide DC power to stabilize the wave treatment to ensure that the inverter will not be damaged, and then through the PWM technology to adjust the electronics, the inverter will not be damaged.
Then through the PWM technology to adjust the periodic changes in electronic components to generate the same frequency as the grid waveform current, and finally to generate the square current to smooth the transformation into a pure sine wave
For the use of inverters only need to provide a stable DC power supply, directly connected to the inverter, of course, in the household electricity to install the blocking appliances and meters, for vehicle use is very simple.
For pure sine wave inverter, we most commonly used to be the car to facilitate the travel camping power experience, of course, as long as there is a power supply you can use at any time.
in the purchase of the inverter will be on the surface of the surface inverter power, which refers to the rated power as long as most of the appliances under the power can be used normally, excluding, for example, inductive loads such as motors and other electrical appliances need to be a large start-up power outside the general 5 times or so can be used normally.
Inductive appliances: air conditioners, pumps, motors, washing machines, fans, drills and so on.
Resistive appliances: white weaving lamps, water heaters, water dispensers, electric kettles, rice cookers, etc.
(1) Simple distinction between the repair sine wave inverter and pure sine wave inverter, in order to prevent sellers from maliciously cheating consumers to pure sine wave inverter price sales repair sine wave inverter caused irreparable losses.
To master the simple way of judgment is necessary to connect the inverter to the battery connected to the fan, if the fan noise is louder than the sound connected to the household power supply is to repair the sine wave inverter
(2) matching, when buying an inverter should be based on the battery voltage to buy the right inverter, for example, 12V ~ 220V used for 12V battery.
The pure sine wave inverter can be used for all household appliances, simple installation is very convenient to use.
