High voltage drive circuit's filter circuit and high voltage drive circuit

The utility model discloses a high voltage drive circuit's filter circuit and high voltage drive circuit. This filter circuit includes: first phase inverter is received first level shift signal and is exported first opposition signal, the second phase inverter is received second level shift signal and is exported second opposition signal, first time delay filter circuit receives first opposition signal and second opposition signal respectively, exports the short delay signal of first short delay signal and second, second time delay filter circuit receives second opposition signal and first opposition signal respectively, exports first long delay signal and the long delay signal of second, first short delay signal and first long delay signal are received to first NOR gate, export first or non - signal, short delay signal of second and the long delay signal of second, output second or non - signal are received to the second NOR gate. This filter circuit can improve the filtering capacity of differential mode no
