In the synchronous " model , based on the idea of polygonal flux linkage locus , by means of constructing the switch state period table of three phrase voltage inverter is required . in the brushless model , the igbt ( isolated gate bipolar transistor ) switch state period table is gained by gal ( generic array logic ) which analyzes the signal of position feed - back 在同步方式下,基于多邊形磁鏈軌跡法的思想,用作圖法求得三相電壓型逆變器的pwm波形序列;在無刷直流方式下,用gal對位置反饋信號(hào)進(jìn)行邏輯綜合,得到開關(guān)管的導(dǎo)通規(guī)律。

The Generic Array Logic (also known as GAL) device was an innovation of the PAL and was invented by Lattice Semiconductor. The GAL was an improvement on the PAL because one device was able to take the place of many PAL devices or could even have functionality not covered by the original range.
