SMPS or switched mode power supply is an electronics device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. The circuit consists of
12v 150w SMPS electronic transformer for halogen lamps. On the market are very similar to halogen driver circuit BJT types of transistors (mje13005) used Halogen Lamps 12V 150W Power Supply For a long time I was going to put this inverter for powering 12V halogen lamps, and finally did it.
The power adapter is small portable electronic devices and electronic and electronic power conversion equipment, usually by the shell, power transformer and rectifier circuit, its output can be divided into AC output and DC- output type ; press connection can be inserted into the wall mount and desktop .
switch-mode design to convert 110V AC input to a 12V DC output. This state-of-the-art technology allows the power supply to operate entirely without a big, heavy internal transformer and results in a
Strymon has solved the switching power supply problem. With our dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering, we have designed a switching power supply that is actually quieter than linear units.
If the power supply hasn't been used in a while, I can plug in the AC end and see the light go on. As soon as I plug in the DC end, the power supply light goes out and the charging light on

Figure 1 the basic of DC switching power supply. Both Q1 and D2 will be passed to a high current, this will work alternately. During the Q1 performance, the current is passed through C8, C9, L1 and Q1, When Q1 stop or open circuit Energy stored in L1 will evolve through D2 and C8, C9 in the same direction, makes the output voltage is constant on all times.
When main power supply is running, then this voltage goes from 12V output through diode D. Stand-By mode In stand-by mode is main power supply blocked by positive voltage on the PS-ON pin through resistor R23 from secondary power supply.

DC 12V describes a 12V battery whether it is full (13.7V) or flat (10V) 400Vac —A figure with the unit (Vac) at the end is a momentary figure without any additional tolerances included. 50Hz vs. 60Hz —As long as not otherwise stated, AC 230V parameters are valid at 50Hz mains frequency.
It's a switching DC supply so its small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip.
A Switching DC power supply (also known as switch mode power supply) regulates the output voltage through a process called pulse width modulation (PWM). The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power effiency and small form factor.

Typical AC to DC regulated switching power adapter While older regulated power adapters are really just like the previously described unregulated transformer type with a linear (analog) voltage regulator built in (and with many of the same limitations), today's modern switch mode regulated power adapters are a big step forward in technology.

Jul 23, 2009One benefit nobody mentioned yet (I don't think) is that switch mode power supplies can be designed to work over a very broad AC input voltage range, like 90 to 260Vac- even without any kind of a tapped transformer or line voltage selection switch.
