Based on the analysis of the affected extent of the neutral-point potential by every space vector on all kinds of voltage and current conditions the concept named neutral point control grade was proposed for the first time in this paper. The calculation formulas of NPCG were presented as well. Based on NPCG, a novel modulation scheme called optimized 3D space vector modulation (O3DSVM) scheme was proposed in a-b-0 coordinates based on the translation principle of axes, by which the space vectors with higher NPCG values are selected to synthesize the object vector to suppress the unbalance of the neutral-point potential.

To determine the role of neutral trehalase during storage stability of spores, we constructed a M.anisopliae RNAi transformant and an overexpression transformant. Analysis of these transformants revealed that the expression level of the neutral trehalase gene in RNAi transformant(No 688) was reduced to 50% of which found in wild type and the overexpression transformant(No 113) showed approximatlely 2-fold higher levels of neutral trehalase mRNA than that found in wild-type control.
