APPARATUS AND METHOD OF CONTROLLING LOW FREQUENCY LOAD CURRENTS DRAWN FROM A DC SOURCE IN A TELECOMMUNICATIONS SYSTEM

摘要

A circuit (Figure 4B) controls the low frequency load currents drawn by components of telecommunications systems. The circuit includes a power converter, a first sense circuit (Vavg input into 412), a second sense circuit (input into 414), a comparator (414), and a power converter control circuit (412). The power converter control circuit controls the power converter's duty cycle in accordance with the input from the first sense circuit and Verror.
