Switch mode power supply Switch mode power supply

Switch Mode Power Supply (SMPS, Electronics transformers) is a low cost regulated flyback power supply, based in a design that directly replaces multiples unregulated linear Power Supplies designs.

The Electronic transformer has an extremely no-load low consumption, high efficiency and advanced safety features like over-voltage, over-current and thermal protection.

Our designs use the same format of encapsulated transformers, so it is suitable to use in the same PCB space. Worldwide universal input, several standard single or multiple output voltages in different case formats.

Power inverters Power inverters

Also so called inverter or ondulator, is an electronic circuit used to turn direct current (DC) into alternating current (AC). The function of an inverter is to change the voltage of entry of direct current (it normally comes from a battery of 12 or 24 Vdc) to an alternate voltage of exit (normally tension of network (net) 110 or 230 Vac).

The inverters are in the habit of being composed of an oscillator that controls a transistor wich is used to interrupt the constant tension of entry and to generate a square wave. This square wave feeds a transformer that adapts the tension level wiched in the exit and a final filter smooth the waveform making it very similar to a pure sine wave. It is also possible to generate modified sine wave, wich is generated from three points: one positive, the negative one and one to ground. Modified since wave inverters can cause less efficiency especially when working with inductive loads.
