Charging and Discharging Test Solution
技术概述
The pdf is a document that introduces a solution for evaluating the electrical characteristics of bidirectional DC/DC converters for 48V micro/mild hybrid vehicles. The solution is the N7900 series Advanced Power System, which is a Keysight product that offers seamless switching between charging and discharging modes, arbitrary input voltage/current and battery degradation simulation, high-accuracy current measurement, and an all-in-one design that simplifies the test environment and improves the measurement reliability. The document explains the test needs and challenges for bidirectional DC/DC converters, and how the N7900 series addresses them with its features and benefits. The document also provides some technical specifications, such as output power, voltage, current, accuracy, sampling rate, and resolution. The document mentions some Keysight models, such as N7909A power dissipater unit, which can be used to extend the output range of the N7900 series. The document also includes some identifiers, such as part numbers, option numbers, and accessory numbers. The document provides some ordering and sales information, such as contact details for Keysight Japan, local Keysight offices, and Keysight website (http://www.keysight.com/find/contactus). The document is intended for customers who are developing or testing bidirectional DC/DC converters for 48V micro/mild hybrid vehicles or similar applications.
