MVD frequency converters use the topology of serial connection of power cells. This topology allows you to flexibly configure the amount of voltage in the phase by changing the number of power cells connected in series. The vector voltage control method with pulse width modulation of the output signal ensures high accuracy and fast response of the control system.
Each MV frequency converter is calculated individually based on a completed questionnaire
Among other features of the medium-voltage drive: Efficiency 98.5 (excluding transformer), easy-to-maintain layout, wide input voltage range, automatic voltage regulation to protect insulation from overvoltage effects, high torque at low frequencies, on-the-fly pickup and power loss compensation functions, optional manual or automatic bypass to ensure trouble-free operation, low harmonics and high power factor.
The VEDA-IN DRIVES medium-voltage variable frequency drive does not require an additional input filter, which significantly reduces investment costs. Due to the high power factor of the frequency converter, it is not necessary to use reactive power compensation devices.
VEDA-IN DRIVES MVD, in addition to classical regulation, have the ability to return electricity to the grid using a heat exchanger.
