  1. Inverters • An inverter is a device transforming AC current into DC currentIf properly controlled, the inverter converts DC Current and reproduce AC current by controlling frequency and voltage. • INVERTER

  2. Inverters • An inverter is a device transforming AC current into DC currentIf properly controlled, the inverter converts DC Current and reproduces AC current by controlling frequency and voltage. R U Mot. ~ S V T W • INVERTER • AC current Variable Voltage and frequencyi.e. 200Vac100Hz • AC current Fixed Voltage and frequencyi.e. 400Vac 60Hz

  3. +VE U ~ R Mot. V S W T -VE Inverters • An inverter is a device transforming AC current into DC current powering an IGBT bridge. If properly controlled,The IGBT bridge reproduces AC current by controlling frequency and voltage. • DC Current • DIODES RECTIFIER • INVERTER • IGBT BRIDGE

  4. Inverters Motion Drives • With a proper feedback an inverter is able to controlthe speed and the torque of the electric motor shaft • Speed measurement R ~ S T • INVERTER

  5. Inverters Brakes • When the inverters reduces the speed of an high inertial load or when the inverters drives an heavy load down power is regenerated into the back into the inverter. • Speed measurement R ~ S T • INVERTER • The inverter is capable of dissipating such power into a braking resistor

  6. Inverters Regenerative • In a Back to Back configuration an inverter can act as a bidirectional Active Front End that is able to regenerate power back into the grid • Speed measurement R ~ S T • INVERTER • AFE

  7. +VE U Mot. V W -VE Inverters Inverters Regenerative • The Active Front End (AFE) is capable of feeding power into the grid • DC Current ~ R S T • INVERTER • IGBT BRIDGE

  8. +VE -VE Photovoltaic Inverters • The Active Front End (AFE) is capable of feeding power power produced by PV modules • DC Current • PV modules ~ R S T • GRID • INVERTER

  9. Photovoltaic Inverters • Most of PV inverters needs a transformer. • In some PV inverters the transformer is included • PV modules +VE ~ R S -VE T • GRID • Transformer • INVERTER • PV INVERTER CABINET
