Battery_charger_that_uses_a_PUT

Published:2009/7/22 4:14:00 Author:Jessie | From:SeekIC

This circuit shows a PUT that is used to control a short-circuit-proof battery charger. Figure 9-27B shows the charging characteristics of the circuit. The charger provides an average charging current of about 8 A to a 12-V lead-acid storage battery. The circuit will not function or will be damaged by improperly connecting the battery because battery current is used to charge timing capacitor C1 (the SCR remains cut off, and the PUT relaxation oscillator does not function until a battery is connected as shown). The maximum battery voltage (10 to 14 V) is set by R2.
