Load supplying circuit arrangement, has resonance converter supplying input voltage derived from intermediate circuit voltage, where compensated intermediate circuit signal is led to input terminals of resonance converter as input signal

摘要

The arrangement has a resonance converter supplying input voltage derived from an intermediate circuit voltage (VZ) to input terminals for supplying a load. A compensation circuit produces an alternating voltage signal that superimposes the intermediate circuit voltage. The alternating voltage signal is produced such that a ripple part is partly extinguished in the intermediate circuit voltage. A compensated intermediate circuit signal is led to input terminals of the resonance converter as an input signal.
