A three-phase rectifier boost circuit and a control method therefor, and an uninterruptible power supply. The circuit mainly comprises a positive battery pack (BAT+), a negative battery pack (BAT-) and a rectifier boost module. The rectifier boost module comprises a first bidirectional thyristor (SCR1), a second bidirectional thyristor (SCR2), a third bidirectional thyristor (SCR3), a first unidirectional thyristor (SCR4), a second unidirectional thyristor (SCR5), a first inductor (L1), a second inductor (L2), a third inductor (L3), a three-phase fully controlled rectifier bridge (11), a first capacitor (C1) and a second capacitor (C2). The present invention realizes the multiplexing of a power level device, increases the power density of a circuit, reduces configurations of a battery, enlarges an application range and improves the reliability of a battery mode. |
