The proposed ON-Line uninterruptible power
supply (UPS) offers AC voltage regulation on continuity
basis which incorporates with the controllable battery
charger. The battery used is Lead Acid Type battery. The
charge control technique used for battery is constant
current charging technique. The Constant Current is
achieved by limiting the duty cyc...

Microcontrollers with embedded timers can directly measure resistive and capacitive sensors by determining the charging or discharging time of an RC circuit that includes the sensor. However, the same as classical signal conditioning circuits, these microcontroller-based interfaces are susceptible to power supply interference. This susceptibility i...

The proposed proposal basically concentrate on energy efficient and cost effective model construct an automatic UPS monitoring and controlling system , with the context of PDA’s to machine level and machine level to PDA’s.RF is the essential information based communication system now a days i.e. Bluetooth/ZigBee/Wi-Fi . IoT based UPS provides the balancing tradeoff between monitoring and controlling the system remotely in order to increase the energy efficiency and production rate. Proposed system automatically monitor the 4 parameters ,i.e current ,voltage, temperature, power which runs on each UPS. During the drain out or worn-out if any of the pa-rameters like voltage andcurrent decreases from the ideal conditions then this will be monitored automatically and the values will be displayed on android app application and and uploaded to the cloud(IoT).The breakdown conditions of UPS will be notified to the chief engineer,supervisor and control room through SMS and IOT.
... The conventional PI controller is used for harmonic reduction in VSI, because the system behaviour is accurate due to reduction of steady-state error, reduction of overshoot, increased bandwidth, etc. In this paper, the ideas are also directly implemented digitally for single phase inverter controlled by PIC microcontroller to reduce total harmonic distortion [24]- [26]. ...
This paper provides overall view of online uninterrupted power supply. The modern day society with growing technology, the work task in many industries and data centers operate on networks and require continuous power supply. Even a momentary drop can cause loss to industry or organization. Hence, uninterrupted power supply is crucial part of system. In this paper the online uninterrupted power supply is designed and simulated for all three modes of operation. The simulation is done using PSIM software in both open and closed loop conditions. The system with a peak power of 5KVA is designed which includes power factor correction circuit, pure sine wave inverter and bidirectional DC-DC converter.
Key words – Online uninterrupted power supply, Pure sine wave, Bidirectional DC-DC converter, PSIM.
