Abstract

Układ miękkiego startu i rozładowania ładunku składa się z mostka prostowniczego (M), dwóch kluczy, rezystora rozładowująco - ograniczającego i kondensatora, w którym napięcie wejściowe dołączone jest do wejść mostka prostowniczego. Ujemne wyjście mostka prostowniczego (M) dołączone jest do styku normalnie zwartego klucza pierwszego (K1), jednego zacisku kondensatora (C) oraz jednego zacisku wyjściowego (WY). Wyjście dodatnie mostka prostowniczego (M) dołączone jest do styku normalnie otwartego klucza pierwszego (K1) a styk przełączny klucza pierwszego (K1) dołączony jest do jednego styku klucza drugiego normalnie otwartego (K2) i rezystora rozładowująco - ograniczającego (R). Drugi styk klucza drugiego normalnie otwartego (K2) dołączony jest do drugiego zacisku rezystora rozładowująco - ograniczającego (R), drugiego styku kondensatora (C) oraz drugiego zacisku wyjściowego (WY).The soft start and discharge system consists of a rectifier bridge (M), two keys, a discharge-limit resistor and a capacitor in which the input voltage is connected to the rectifier bridge inputs. Negative bridge rectifier output (M) is connected to the contact of a normally closed first key (K1), one capacitor terminal (C) and one output terminal (WY). The positive output of the rectifier bridge (M) is connected to the contact of the normally open first key (K1) and the switch contact of the first key (K1) is connected to one contact of the second normally open key (K2) and the discharging and limiting resistor (R). The second contact of the second normally open key (K2) is connected to the second terminal of the discharging and limiting resistor (R), the second contact of the capacitor (C) and the second output terminal (WY).
