The Solution for Frequency Conversion

To convert 50hz to 60hz, we use a two-stage power conversion process to assure that the output voltage is precisely regulated and isolated from noise and disruptions on the input AC power source. As shown in the figure below, the input AC power is processed through an AC-to-DC power converter that assures the input power factor is as close to one as possible. This reduces the current on the input source, providing the environmentally friendly benefit of reducing the carbon emissions from the electric power provider.

The output of the AC-to-DC converter is provided an energy storage bank. The energy storage bank keeps the output load supplied with power even if the input power should be momentarily interrupted.

The output of the energy storage bank is connected to a DC-to-AC converter (also known as an inverter) that generates a pure sine wave output of 120V 60Hz.

For clarity, not shown in the diagram are the input and output filters that limit electrical noise emitted into the input and output AC power and the input and output protection circuits.
