Inverter drives power devices through PWM with different pulse widths.

Fully controlled switch refers to more IGBT modules. Generally, IGBT modules are used for high power. . .

IGBT is driven by voltage. Generally, there are more ++ 15V and -5V drivers.

At present, there are two basic ways of inverter, through PWM special chip. The corresponding modulation signal is generated by single chip microcomputer or other analog circuits to modulate the PWM chip, so that the PWM chip can generate SPWM driving waveform.

There are also corresponding SPWM driving waveforms directly generated by single chip microcomputer or DSP, and then amplified and shaped by the driving circuit for driving.
