When a single diode is used as a rectifier, does it provide a constant current?
Rectifiers that use just a single diode suffer from high amounts of ripple, which is generally undesirable in AC to DC conversion. When utilizing only one diode, the resulting current will only be half wave, which essentially means half of the available energy. Although technically no rectifier provides a 100% constant voltage and all rectifiers have ripple in their output, typically a single diode circuit will lead to the most amount of ripple and the least constant current.
