Page 10: Principle Of Operation
PAGE 10 / 3 6 Principle of operation This Online UPS system contains 3 major PCB assemblies. They are including: 1. PSDR: contains major parts of (1) DC power supply (2) DC-DC converter, (3) inverter (4)Input and output circuits. 2. CNTL : contains major parts of protection, signaling circuits, regulation and control circuits of inverter... - Page 11 PAGE 11 / 3 Figure 2: Block Diagram for UPS. 1.POWER STAGE (PSDR) As shown in figure1,the power stage consists of DC power supply, DC-DC converter, inverter, Input and output circuits. 1-1 DC Power Supply Sub-System: The input of the DC power supply is connected to the battery bus, i.e., the output of the charger.
- Page 12 PAGE 12 / 3 To construct a high frequency (19.2kHz) PWM inverter, the drivers receive switching signals from PWM generation circuit through 2 PWM ICs to trigger the four IGBT alternately. The output of IGBT is filtered by an LC circuit to reduce the o/p voltage harmonics distortion.
