FAQS 4
What are the characteristics of a pure sine wave inverter?
Key characteristics of a pure sine wave inverter: Clean and Smooth Output: A pure sine wave inverter generates a clean and smooth AC output waveform, which is nearly identical to the type of electricity supplied by utility companies. This makes it suitable for running a wide range of electrical and electronic devices.
What is a modified sine wave inverter?
Modified sine wave inverters use simpler and cheaper electronics to produce a wave that is not quite a smooth sine wave. Pure sine wave inverters use more expensive electronics to generate a wave that is very close to a pure sine wave. The figure below compares outputs from a modified sine waver inverter and a pure sine wave inverter.
How do sine wave inverters work?
Sine wave inverters work in three stages: the oscillator stage, the booster or amplifier stage, and finally the transformer stage. The oscillator stage does what the title says it does: changes the DC current to an oscillating AC current. The oscillating current can be set to a particular frequency: for the United States the frequency is 60 Hz.
How to generate a pure sine wave output from an inverter?
We use the Sinusoidal Pulse Width Modulation (SPWM) technique to generate a pure sine wave output from the inverter. We use the PIC16F877A microcontroller to generate SPWM. Then, feed these SPWM waves to the MOSFETs of the H bridge.
