The utility model discloses a converter low voltage ride through supporting arrangement based on super capacitor. Some power system fault arouses that great voltage dip can lead to the shut down of mill's converter at present. The utility model discloses a characterized in that, the super capacitor energy storage unit link to each other with converter direct current link through the contrary diode that ends, utilize the unidirectional flux nature of diode, prevent that converter rectifier unit from undertakeing extra super capacitor charging current, ensure energy that super capacitor stored only during voltage falls output give the main circuit, super capacitor battery charging unit's inlet side and alternating current power supply are connected, outlet side and super capacitor energy storage unit connection, super capacitor voltage -sharing unit and super capacitor energy storage unit connection. The utility model discloses can make ordinary converter possess the low voltage ride through ability, can satisfy each industry field converter low voltage ride through's support requirement.
