Use of Direct-Current Voltage Converter to Maintain Constant 27.5-Volt Terminal Voltage from Lead Acid Battery Power Supply

摘要

The report covers an investigation of the use of an engineering design model voltage converter to maintain a 27.5-volt terminal voltage from lead acid batteries varying in voltage from 24 to 20 volts. The report concludes that: (a) A direct-current voltage converter can maintain a 27.5-volt terminal voltage from a lead acid battery source varying in voltage from 24 to 20 volts; (b) A direct-current voltage converter and 24-volt lead acid batteries in parallel with a 28-volt, direct-current, engine-driven automotive alternator or generator set provides a no-break power supply that will permit shutting down the engine-driven unit for maintenance or service without any variation in system terminal voltage; (c) The combination of lead acid batteries and a direct-current voltage converter can act as 'peaking power' to carry momentary surge leads or 100-percent overloads on an alternator or generator set for short periods, permitting the use of a smaller engine-driven unit than would otherwise be required.
