This situation causes the bridge rectifier to turn into a voltage doubler, which enables the output to continue to be at around V DC level. The 22V zener is used for generating a reference voltage, and the netwrok using the 1N diode and the 22 pF capacitor is used like a single phase rectifier stage. This is maintained even at relatively higher input voltages up to V. When the AC input exceeds this higher level, the base potential of BC increases to a level which is enough to switch it ON.
The changeover happens at around V input, when the opto-triac device BRT12 becomes non conductive. Seldom use, totally like new. It can be used with any kind of appliance or device up to watts, like air compressor, sewing machine, rice cooker, CPAP Machine etc.

Thus the circuit can be used for setting the input voltage at the required V level. Alternatively a simpler version of the circuit can be made, where the main high triac is operated via a cheap light dimmer switch for the intended results.
The following image suggests how a simple high value capacitor can be used for achieving the intended V to V output. It is basically a triac crowbar circuit where the triac shunts the extra V to ground allowing only V to come out across the output side:.
The last circuit in the order is perhaps the safest from the above because it uses the conventional concept of transfering power through magnetic induction, or in other words here we employ the age old autotransformer concept for making the desired V converter. However here we have the freedom of designing the core of the transformer such that it can be stufed inside the particular gadget enclosure which needs to be operated from this converter. There will be always some space in gadgets like an amplifier or other simlar systems, which allows us to measure the free spave inside the gadget and customize the core design.
I have shown the use of ordinary steel plates here as the core material which are stacked together and bolted across two of the sets. The bolting of the two sets of lamination provides some sort of looping effect, generally required for efficient magnetic induction across the core.
The winding a single long winding from start to end, as shown in the figure. The center tap from the winding will provide the required approximate V AC output. The next circuit has been taken from an old elektor electronic magazine which describes a neat little circuit for converting V mains input to V AC. Let's learn more about the circuit details. The shown circuit diagram of a transformerless v to v converter utilizes a triac and a thyristor arrangement for making the circuit successfully work as a v to v converter.
The right end of the circuit consists of a triac switching configuration where the triac becomes the main switching element. The resistors and the capacitors around the triac is kept for presenting perfect driving parameters to the triac. The left section of the diagram shows another switching circuit which is used to control the switching of the right hand side triac and consequently the load.
The transistors at the extreme right of the diagram are simply there to trigger the SCR Th1 at the right moment. The supply to the entire circuit is applied across the terminals K1, via the load RL1 which is in fact a V specified load. Initially the half wave DC derived through the bridge network compels the triac to conduct the full V across the load. However in the course, the bridge starts getting activated causing an appropriate level of voltage to reach the right hand section of the configuration.
This causes short circuiting of the bridge output, choking the entire trigger voltage to the triac, which finally ceases to conduct, switching off itself and the entire circuit. The above situation reverts and restores the original state of the circuit and initiates a fresh cycle and the system repeats, resulting in a controlled voltage across the load and itself.
The transistors configuration components are so selected that the triac is never allowed to reach above the V mark thus keeping the load voltage well within the intended limits. The circuit is recommended for operating resistive loads only, rated at V, below watts. If you have any circuit related query, you may interact through comments, I'll be most happy to help! Your email:. Have any circuit for that? Or, is it possible to change the winding of the transformer to change to V?
