DC/DC变换是将可变的直流电压变换成固定的直流电压，也称为直流斩波。斩波器的工作方式有两种，一是脉宽调制方式Ts不变，改变ton(通用)，二是频率调制((1)Buck电路——降压斩波器，其输出平均电压U0小于输入电压Ui，极性相同。(2)Boost电路——升压斩波器，其输出平均电压U0大于输入电压Ui，极性相同。(3)Buck-Boost电路——降压或升压斩波器，其输出平均电压U0大于或小于输入电压Ui，极性相反，电感传输。(4)Cuk电路——降压或升压斩波器，其输出平均电压U0大于或小于输入电压Ui，极性相反，电容传输。还有Sepic、Zeta电路。

电源模块是隔离、保护(短路保护、过压保护、欠压保护、过流保护、其它保护、)电压交换、稳压、降噪等功能。尽管每个电源模块的负载电流突然减小，系统的输出功率都不会因此而受到任何影响。电源模块带电插入时，在所有输入和输出端都接通以前，变换器暂时维持关断状态。否则在热插拔时，连接器接触点无规律的通断都有可能损坏变换器模块，严重时甚至是损坏整个系统。

DC/DC conversion is the process of converting a variable DC voltage into a fixed DC voltage, also known as DC chopping. There are two working modes of choppers: one is the pulse width modulation mode Ts, which remains unchanged and changes to ton (universal), and the other is frequency modulation ((1) Buck circuit – buck chopper, whose output average voltage U0 is smaller than the input voltage Ui and has the same polarity. (2) Boost circuit – a boost chopper with an average output voltage U0 greater than the input voltage Ui and the same polarity. (3) Buck Boost circuit – a buck or boost chopper with an average output voltage U0 greater than or less than the input voltage Ui, opposite polarity, and inductive transmission. (4) Cuk circuit – a buck or boost chopper with an average output voltage U0 greater than or less than the input voltage Ui, opposite polarity, and capacitive transmission. And Sepic and Zeta circuits

The power module is used for isolation, protection (short circuit protection, overvoltage protection, undervoltage protection, overcurrent protection, other protection, etc.), voltage exchange, voltage stabilization, noise reduction, and other functions. Although the load current of each power module suddenly decreases, the output power of the system will not be affected in any way. When the power module is plugged in with power, the converter temporarily remains turned off until all input and output terminals are connected. Otherwise, irregular on-off of the connector contact points during hot swapping may damage the converter module, and in severe cases, even the entire system.
