大功率电源大至由主功率电路、PWM控制电路、单片机控制电路、辅助电源四大部份组成。
主功率电路
冲击电流限幅：限制接通电源瞬间输入侧的冲击电流。输入滤波器：其作用是过滤电网存在的杂波及阻碍本机产生的杂波反馈回电网。
整流与滤波：将电网交流电源直接整流为较平滑的直流电。
逆变：将整流后的直流电变为高频交流电，这是高频开关电源的核心部分。
输出整流与滤波：根据负载需要，提供稳定可靠的直流电源。
PWM控制电路
一方面从输出端取样，与设定值进行比较，然后去控制逆变器，改变其脉宽或脉频，使输出稳定，另一方面，根据测试电路提供的数据，经保护电路鉴别，提供控制电路对电源进行保护措施。
单片机控制电路
单片机使用ADC对输出电压电流采样，并通过DAC输出控制输出电压电流的变化，并对整个电源运行状态进行监控，并负责与电脑连续。
辅助电源
实现电源的软件（远程）启动，为保护电路和控制电路（PWM等芯片），单片机工作供电。
