Harmonics
Each power supply unit transforming an AC (line) voltage in a DC voltage in order to supply
electrical loads generates unwanted harmonics. The functioning mode of the power supply
unit used has no influence on the generation of harmonics.
Harmonics, which are generated by rectifiers with downstream smoothing capacitors or
primary-switched mode power supply units, will be fed back into the electrical supply
network if no appropriate limiting measures are taken. This affects sensitive electronic
loads. Harmonics cause the power consumption of the loads to increase. Cable cross
sections would unnecessarily need to be designed larger.
Harmonics are caused by a pulse-shaped current, which is generated by the current
consumption of rectifiers with a downstream capacitance or primary-switched mode power
supply units.
A simple rectifier with diode D1 and capacitance C1 is shown in Figure 3-33. The time
history of voltage and current is shown in Figure 3-34. The U in AC voltage is rectified by
diode D1 and smoothed by capacitance C1. The pulse-shaped current I in is generated
when capacitance C1 is recharged with a positive half wave of the input voltage U in . The
capacitance is always recharged when the supply voltage U in is higher than the voltage U C
across capacitance C1.
