Dc Bus Voltage
The dc link bus voltage in VSIs is usually considered a constant voltage source v i. Unfortunately, and due to the fact that most practical applications generate the dc bus voltage by means of a diode rectifier (Fig. 15.37), the dc bus voltage contains low-order harmonics such as the sixth, twelfth,…(due to six-pulse diode rectifiers), and the second if the ac voltage supply features an ...
electrical system
The common battery voltage on aircraft is commonly referred to as "28 volts". What does that really mean in terms of a lead-acid battery? In many uses, such as cars ("12V"), trucks ("24V") forklifts and golf carts ("36V" or "48V"), locomotives ("64V"), the nameplate number is exactly twice the number of lead-acid "cells".
