Non-inductive DC step-down converter using capacitors for telecommunications

摘要

The non-inductive DC current step down converter has switches (S1, S2) for charging and discharging the capacitors (C), controlling the rising and falling flanks of the pulses of a rectangular pulse generator (TG). The first switch (S1) for the charging of the capacitors is formed by a first transistor (T1) and a diode (D1) allocated to each capacitor. The second switch (S2) for the discharging of the capacitors is formed a second transistor (T2) allocated to each capacitor and a diode (D2). The first transistor (T1) has a transistorised level converter (PW) connected in front of it.
