In general, battery chargers take standard AC power and convert it into DC power, which is then stored in the battery for use. Unlike traditional motive chargers, like ferroresonant, silicon controlled rectifier (SCR) and certain hybrid varieties, high-frequency chargers are simply more efficient.
Battery chargers convert standard AC power to DC power to store in a battery. High frequency chargers use more advanced circuitry to convert the power at higher frequencies, which reduces conversion losses and improves charging efficiencies. What are the most appropriate applications?
In most cases, high frequency battery chargers will have a higher power factor than the existing chargers, especially when compared to SCR. If the customer has a large number of chargers and power factor issues, this could help facility power factor and reduce power factor charges.
High-frequency battery chargers have a higher power factor than traditional chargers. The power factor, which measures efficiency, ranges between 0 and 1, with 1 being the most efficient. To determine the rating, you compare the power the charger draws to the power the charger uses during charging. Are HF chargers worth the extra cost? YES
Switching from standard SCR or ferroresonant chargers to high frequency chargers leads to standard savings of about 7%. This is based on average equipment efficiencies, but it is not uncommon to see savings upwards of 15% depending on the specific existing and new equipment efficiencies.
In order to induce HF AC voltages and currents in the secondary circuit, the EMFs produced by the transmitter coil are coupled with the receiver coil (in the vehicle). To charge the vehicle’s battery packs, the HF secondary AC power is then rectified.
