The effect on the zero voltage transition PWM converter caused by parasitic capacitance and its elimination method

寄生电容对 零电压过渡PWM电路影响及 对策

The coefficient matrix of the linear equations is nonpositive definite because of the restrictions but we prove the leading principal minors of the matrix do not equal zero and the triangular decomposition or Gaussian elimination can be used to the linear equations .

由于约束条件的缘故，导出的线性方程组的系数矩阵不是正定的，但本文证明了它的各阶顺序主子式不等于 零，从而可用三角分解法或高斯 消去法。
