目前主流的伺服驱动器均采用数字处理器（DSP）作为控制核心， 可以实现比较复杂的控制算法，实现数字化、网络化和智能化。功率器件普遍采用以智能功率模块（IPM）为核心设计的驱动电路,IPM内部集成了驱动电路,同时具有过电压、过电流、过热、欠压等故障检测保护电路,在主回路中还加入软启动电路,以减小启动对驱动器的冲击。功率驱动单元首先通过三相全桥整流电路对输入的三相电或者市电进行整流，相应的直流电。经过整流好的三相电或市电，再通过三相正弦PWM电压型逆变器变频来驱动三相永磁式同步交流伺服电机。功率驱动单元的整个可以简单的说是AC-DC-AC的。整流单元（AC-DC）主要的拓扑电路是三相全桥不控整流电路。
