A pure sine save inverter can offer appliance below:
Pure sine wave inverters cover all appliance, make sure the inverter power is bigger than all home appliances. Click here to understand how to read a inverter data sheet.
The inverter generates oscillating pulses through an IC circuit in this stage. Alternate positive and negative voltage peaks generate by these oscillations with a particular frequency. They are very weak and can never be used to power up high current output transformers.So these pulses are sent to the amplifier of the inverter for the required task.
The alternate voltage generated by pure sine wave inverter oscillator amplified to high current levels in this stage. Amplified electricity is in AC form, the voltage is still at the battery supply level, which is too low to operate an electrical appliance. To raise the voltage to levels that is suitable for electrical appliances, the amplified voltage is applied to the output transformer secondary winding.
In an AC to DC transformer, the power supply is reduced or stepped down to lower specified AC levels through the magnetic induction of the transformer’s two windings. The transformer in a power inverter works in a similar way, but in a reversed manner.
The low level AC power from the amplifier stage of the inverter is applied to the secondary windings of the transformer in the output transformer stage. This process results in an induced stepped up voltage, which is used by power inverter to power AC appliances.
A modified sine wave inverter can work well for ordinary equipment and appliances,
A modified sine wave inverter can be seen for cars. Which convert DC current from car battery to AC for other home appliances.
Like we mention, using the modified sine wave inverter will have noise, and some appliance will be damaged or over heated if long time using.
