Inverter Applications Inverters Convert DC to AC

DC FILtering At Input 60 Hz AC is rectified to DC with high ripple AC Most electronic applications do not perform well with high AC ripple. A filter, capacitor is placed between the rectifier and the load to smooth the voltage by filtering out much of the unwanted AC.

Inverter Applications Inverter switching produces ripple voltage across the capacitors resulting in high ripple current. Total ripple current is from rectification and switching Ripple current heats the capacitor (blue peaks below) Higher temperature shortens capacitor life

Focus on Inverter Applications Inverters Convert DC Voltage Into AC Voltage INVERTER Renewable Energy Wind Solar Fuel Cells Industrial Welding Lasers Semiconductor Processing Motor Drives Elevator Industrial Motor Drives Electric Vehicles Power Backup UPS Flywheel Battery Chargers SMPS Most solar and wind inverters use film capacitors for DC Link 10
