    Design and Implementation of a Sine Wave Instant Power Supply
    (IIUC Central Library, 2011-06-18) Chakma, Rocky; Alam, Rashedul
    The aim of this project is to make a sine wave instant power supply and analysis the effect of different types of load on home appliances. There are many types of Instant power supply (IPS) in the market. Most of these outputs are PWM and the efficiency of these are less than sine wave IPS. But the sine wave instant power supply (IPS) are costly than other instant power supply. The instant power supply mainly contain with two parts. The first one is inverter part which convert 12VDC to 220VAC.The second part is battery charging part which charge the DC source. The output from the inverter part is sine wave. The efficiency of this sine wave instant power supply is better because output of the other instant power supply is square wave. This instant power supply is cost effective than other types of instant power supply.
