Detail
Inverter is a kind of semiconductor device composed of electric power adjustment device, mainly used for DC power
Converted into AC power. Generally consists of boost circuit and inverter bridge circuit. The
booster circuit boosts the DC voltage of the solar cell to the DC
voltage required for the inverter output control. The inverter bridge
circuit converts the boosted DC voltage to the AC voltage of the common
frequency. The inverter is mainly composed of a
switching element such as a transistor, and turns the DC input into an
AC output by repeatedly turning ON-OFF the switching element in a
regular manner. Of course, it is not practical to simply output the inverter output waveforms from the on and off circuits. It
is generally necessary to use high frequency pulse width modulation
(SPWM) so that the voltage width at both ends of the sine wave becomes
narrower and the voltage width in the center of the sine wave is widened
and the switching element is always operated in a direction at a
certain frequency in a half cycle, A pulse wave train (pseudo sine wave). And then let the pulse wave through a simple filter to form a sine wave.
