Smart On-Line — Double Conversion Principle

Smart On-Line are built on the double conversion principle. Double conversion is an effective way to make the output completely independent of the input network's condition. The network may have significant instability, interference, and any other distortions, but this signal is converted to DC current and is 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 power factor corrector is necessary to avoid overloading the network with large impulse currents.

In the second stage, the output AC 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 a stable voltage level with a deviation of no more than 1% from the value set by the user. A stable frequency of 50 Hz is also maintained, regardless of input voltage fluctuations.

The stabilizer is capable of delivering a clean signal without any interference at any given moment. When connected to a generator, it provides a correct sinusoidal voltage waveform. This feature is extremely important when connecting asynchronous motors and transformer power supplies, as a distorted power supply voltage waveform leads to their overheating.

The constancy of the output voltage and the wide range of input voltage make stabilizers with double energy conversion the only correct solution for powering servers, industrial controllers, and other sensitive and critical equipment.
