  12. Inverter Once the power fluctuates outside the boundaries a control switch will allow the inverter power to transfer to the circuit.

  13. Power Inverter • The job of this inverter is to transfer 12Vdc to 120Vac. • This device will always be on • Control switch will allow inverter power to flow

  14. Signal Table • Analog and digital interfacing – N/A

  23. Main Purpose • Keep a constant charge in the battery so when commercial power is lost, the device to which the UPS is connected to stays on for about a half hour or until the battery drains completely. • Provide 5 VDC logic to the CPU which power s all essential controls and sensors.

  24. Power Inputs and Outputs • Transformer Input : 120 VAC / 20Amp • Transformer Output / Rectifier Input : 15.7 VAC (Step Down) • Rectifier Output #1 : 14.3 VDC • Rectifier Output #2 : 5 VDC

  30. Transient Response

  31. Maximum WV for Capacitors • Referencing to the manufacturer (Digikey) specification the following value was chosen as WV. • 470uF Capacitor: • WV : 10VDC • Leakage Current: 235uA • Ripple Current: 570mA • Dimensions: 32(L)*10.3(D)*0.8(d) mm

  32. Power Ratings • Diodes: P = V*I P = (16V)*(2A) = 32W • Resistors: They were only placed in Pspice simulation in order to have the transformer work properly and give accurate results.

  33. Capacitor Tolerance • This Solid Axial 470uF Capacitor has a range of small long life (20000H). • Tolerance±20% and ±10% on request • Usable Temperature range:-80oC to +125oC

  34. Off Board Connectors • Battery Post: To achieve a mechanically secure and tight connection we’ll be using adjustable clamps. • Transformer: It will be sitting on a hard surface at the bottom of the UPS, we’ll use flat pin connectors to connect wires going to the rectifier. • DC to DC Connector: Flat pin connectors.

  35. Charge Type • Trickle Charge : Constantly supplies the battery with 14.3 VDC at 2 Amps. • Logic Charge : Constant +5 VDC converted from the 12 VDC coming out of the battery, this will power CPU, sensors and interface.
