  39. gourav jas says:

    hello!! can i know about UPS and 3 point starter its abstract and how to make this is as mini project to me

    1. 3 point starter is used for DC motors because of back emf , which plays a critical role in governing the operation of the motor. The back emf, develops as the motor armature rotates in available magnetic field, by generating action and counters the supply voltage. The back emf at the starting is zero, and develops gradually as the motor gains speed. For AC motors it is soft start—Refer to

      UPS Uninterrupted power supply

      UPS are available in many different forms depending on how the power conversion is achieved and how the change over from external to internal supply takes place. Typical configurations include:

      An on-line UPS converts AC line power to DC to keep a battery charged and inverts DC battery power to produce AC. The load is continuously fed from the constant battery power, regardless of supply conditions. Because the whole of the supply is converted twice, this type of UPS is relatively inefficient and is used only for small units.

      An off-line UPS feeds the load from the mains supply when it is available. The inverter/converter is normally inactive until a disruption occurs, when the battery delivers power to the inverter, which converts the DC power back to AC power for the load. The drawback is that the time needed to transfer from AC to battery can present a problem for some sensitive equipment such as computers and servers.

      A line-interactive design combines the characteristics of on-line and off-line designs. The inverter in this design performs a dual function. Under normal operation, it keeps the battery fully charged. When a power supply failure is detected, the inverter is disconnected from the supply and power is provided from the battery through the inverter to the load. Similar to an off-line UPS, line-interactive technology is efficient because power is normally supplied directly from the line. Heat and stresses are minimized because the line-interactive UPS delivers only incremental power, compensating for line voltage sags via the output transformer. Like the on-line UPS, it also provides continuous power. However, the line interactive UPS does not provide the complete isolation between the line and load that is offered by the on-line UPS.
