摘要
介绍一种快速的用于三相电压型逆变器SVPWM算法。该算法利用Kohonen神经网络的优点,可快速实时判定主、辅矢量及作用时间,降低输出PWM谐波,并具有可全硬件实现的优点。利用专用DSP芯片TMS20F240实现该算法。
A new algorithm of space vector PWM for three-phase voltage inverter is described. This algorithm takes the advartages of Kohonen neural network to calculate the actuating duration of adjacent switching state vector fast and reduce the harmonic in PWM waveform. It can be implemented by all hardware and the realization by TM320F240 DSP is introduced in the paper.
