The capacitor filter circuit is applicable for small load currents. Half Wave Rectifier with Capacitor Filter. The main function of half wave rectifier is to change the AC (Alternating Current) into DC (Direct Current). However, the acquired output DC is not pure and it is an exciting DC. This DC is not constant and varies with time.
Another common capacitor type is the film capacitor, which features very low parasitic losses (ESR), making them great for dealing with very high currents.
