Tips of Frequency conversion Technology（1）

What is a converter?

Frequency converter is a power control device which converts the power frequency power supply to another frequency by using the on-off action of the power semiconductor device.

What is the difference between PWM and PAM?

PWM is the abbreviation of Pulse Width Modulation, which changes the pulse width of the pulse train according to certain rules. A mode of adjusting values to adjust output and waveforms. PAM is the abbreviation of Pulse Amplitude Modulation, which changes the pulse amplitude of the pulse train according to certain rules. A modulation that adjusts output values and waveforms.
