Smart On-Line — Double Conversion Principle

Smart On-Line systems are built on the double conversion principle, which makes the output completely independent of the input grid's condition. Even with significant instability and interference, the input signal is first converted to direct current and not passed to the output.

In the first stage, capacitors are charged with a constant voltage using a rectifier with a power factor corrector. The corrector is necessary to avoid overloading the grid with large pulse currents.

In the second stage, the output alternating voltage of ideal sinusoidal waveform is formed from the constant voltage using the pulse-width modulation method.

The stabilizer works equally effectively with active, capacitive, and inductive loads, maintaining voltage deviation of no more than 1%. The frequency is stably maintained at 50 Hz, regardless of input voltage fluctuations.

The device outputs a clean signal without interference at any time. When connected to a generator, the stabilizer forms a correct sinusoidal voltage waveform, which is especially important for asynchronous motors and transformer power supplies, as voltage distortions cause them to overheat.

The stability of the output voltage and a wide range of input values make stabilizers with double energy conversion a reliable solution for servers, industrial controllers, and other sensitive equipment.
