With pure sine wave output, NK series inverter can provide stable power for general applications included PC,
ITE, vehicles, yachts, home appliances, motors, power tools, industrial control equipments, AV systems and etc
The function of the inverter is to convert direct current into alternating current. It consists of inverter bridge, SPWM wave module, drive module and filter circuit. The SPWM inverter circuit is the key to generating pure sine wave. The generation of SPWM wave module has always been a research hotspot. SPWM is a pulse width modulation technology, that is, a pulse waveform with a variable duty cycle. The PWM control technology is based on this conclusion. Control the turn-on and turn-off of the semiconductor switching device, so that the output terminal gets a series of pulses with equal amplitude and unequal width!
To obtain the required waveform equivalently, when performing pulse width modulation! If the pulse is used The duty cycle of the series is arranged according to the sinusoidal law, and the output voltage can be filtered to obtain a sinusoidal waveform! At the same time, the harmonic components in the load current are greatly reduced, which is called sinusoidal pulse width modulation.
