Controlling and various the width on the pulses is how PWM differs the output frequency and voltage to attain VFD control.
A VFD can be employed to regulate the electrical frequency (Hz) of the ability equipped to pressurization enthusiasts to ensure that the quantity of air pressure exerted on staircases and carry lobbies through a fire is often controlled.
This is completed to smooth out the electrical waveform which presents the clear power provide for the subsequent move. Electricity then flows from the capacitors for the inverter, that improvements the DC power towards the output AC electrical power that goes towards the motor.
