摘　　要：油田钻机是石油天然气勘探开发的主要设备,本文根据油田钻机变频调速系统的要求,专为其设计了一种具有高可靠性数字控制的逆变器。在分析了电压空间矢量脉宽调制(SVPWM)的原理和其算法实现的基础上,阐述了DSP生成SVPWM波的控制算法,结合油田钻机变频调速启动转矩大、启动电流小、耐负载冲击力强的特点,应用TI公司的TMS320LF2407A芯片,给出了逆变器软硬件的设计方案,通过实验说明其达到了预期的设计要求,并对油田应用效果和其未来的前景作出了简要的说明。Oil rig as oil and gas exploration and development of major equipment, according to this article oil rig frequency control system requirements, specially designed with a highly reliable digital control of the inverter. After analyzing the voltage space vector PWM （SV PWM） principle and its algorithm based on the DSP on the formation of the wave SV PWM control algorithm, combined with oil rigs frequency torque to start, start small current, resistance the impact of the power load characteristics of the application of TI＇s chips TMS320LF2407A, given inverter hardware and software design through its experiment had met the design requirements and application fields and its future prospects and made a brief note.
