The Classification of UPS
The UPS classification methods varied, according to the power size can be divided into large and medium-sized mistress power capacity; the output waveform can be divided into square wave, trapezoidal wave or sine wave; according to the input and output can be divided into single phase into single-phase, three-phase to single-phase or three-phase to three-phase; according to the work principle can also be divided into dynamic UPS and static UPS two categories. Dynamic uninterruptible power supply is dependent on inertial flywheel stored energy to maintain the load power supply continuity, the uninterruptible power supply with heavy, large noise, low efficiency, long switching time and other shortcomings, has been replaced by a static uninterruptable power supply. Static UPS to batteries as the energy storage tool, city normal AC power is rectified into a DC electrical and electrical energy stored in the batteries, when the utility power is cut off by the inverter will be stored in the storage battery DC power into AC power to maintain power to the load. According to the different working modes, static UPS can be divided into the backup UPS, on-line UPS, online uninterrupted power supply systems and Delta transformation uninterrupted power supply four kind of types.
