7. Inverter Applications Inverters Convert DC to AC

8. 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.

9. 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
