Section I: PW series Product System Overview
1.1 Introduction
PW is a high-performance and fully digital UPS utilizing the double DSP control
technology with the power factor correction function. Its performance indexes reach the
leading level of the industry and the power grade contains 15-80 KVA. PW UPS is
connected between the commercial power and the important load to supply the
high-quality power to the load. It adopts the high-frequency double conversion pulse
width modulation（PWM） and fully digital control technology, the output voltage is not
influenced by the change and interference of the input voltage and frequency of the
utility.
As shown in diagram 1, the utility is inputted from CB1, the rectifier converts the
utility to DC .The PFC converts the low DC to high DC ( DC busbar ) and supplies
power to the DC/DC battery charger (charge the battery at any time) and the inverter. The
inverter converts the DC power to AC power to supply the load. When the utility is
interrupted, the battery supplies the back-up power to the load through the battery switch,
PFC and inverter. When inverter is fault or overload time is finished, the external bypass
supplies power to the load through the input switch CB2 and static bypass. In addition,
for the maintenance and repair of the UPS, UPS will supply the power to the load through
the internal maintenance bypass. When the UPS is in normal mode, all switches are
closed except the maintenance bypass switch.

connected in series and one is the host (subordinate UPS), the other is slave (superior
UPS). Besides, the host and slave are determined by the connection of power cable and
setting of allocation software. Normally, the host and slave are operated of inverted
supply mode, and the output of the slave UPS single machine connects to the bypass
input of the host UPS. The output of the host UPS is to be connected with the load, and
synchronize with slave UPS. When the inverter of host UPS connected with the load
happened with fault, power supply will be provided by the slave UPS for the load through
the bypass of host UPS. Moreover, the system can be set to make the host UPS run
alternatively with inverted supply and bypass modes, so that the two UPS can provide the
power supply for the load through alternative operation.
Note: As for the hot backup system, the first thing is to start up the host.
