achieved using an auxiliary switch‚ a diode and a coupled inductor. The main drawback of the circuit is that in order to achieve ZVS in one switch‚ a number of components have to be added to the circuit. In [12]‚ ZVS is achieved in the switch using a transformer‚ thus the voltage stress is reduced. In this

sensing section and this could seriously affect the circuit’s performance. [pic] A regulated 9V/500mA power supply that can be used for powering the basic fire alarm circuit and its modified versions is shown above. Transformer T1 is a 230V primary‚ 12V secondary‚ 500mA step down transformer. D1 is a 1A bridge which performs the job of rectification. Capacitor C1 filters the rectifier output and C2 is the AC by-pass capacitor. IC1 (7809) is a 9V fixed positive voltage regulator. The output of the rectifier+filter

suppression network is thus used to suppress these electrical noises. HISTORY : Light dimming is based on adjusting the voltage which gets to the lamp. Light dimming has been possible for many decades by using adjustable power resistors and adjustable transformers. Those methods have been used in movie theatres‚ stages and other public places. The problem of those light controlling methods have been that they are big‚ expensive‚ have poor efficiency and they are hard to control from remote location. The
