Abstract	本发明公开了一种五电平逆变器及五电平逆变系统。该五电平逆变器包括：第一电容、第二电容、第三电容和第四电容；第一开关组、第二开关组、第三开关组、第四开关组、第五开关组和第六开关组；第五电容，第五电容的一端与第五开关组的一端电连接，第五电容的另一端与第五开关组的另一端电连接；第一二极管，第一二极管的一端与第四开关组的一端电连接；第二二极管，第二二极管的一端与第一二极管的另一端电连接，第二二极管的另一端与第四开关组的另一端电连接。本发明通过分别控制第一开关组至第六开关组的导通或关断状态，实现了五电平逆变器输出端输出五种状态的电平。
Other Abstract	The invention discloses a five-level inverter and a five-level inverter system. The five-level inverter comprises a first capacitor, a second capacitor, a third capacitor and a fourth capacitor, a first switch group, a second switch group, a third switch group, a fourth switch group, a fifth switch group and a sixth switch group, a fifth capacitor having one end electrically connected with one end of the fifth switch group and the other end electrically connected with the other end of the fifth switch group, a first diode having one end electrically connected with one end of the fourth switch group, and a second diode having one end electrically connected with the other end of the first diode and the other end electrically connected with the other end of the fourth switch group. According to the five-level inverter, the on or off states of the first switch group to the sixth switch group are respectively controlled, so that the output end of the five-level inverter outputs levels in five states.
