Transoners can be categorized into two different general applications, identified as the Power Transoner and the Wide Band Transoner.

WIDE BAND Transoner

The first of two distinct modes of operation of Transoner is a Wide Band mode, suitable for telecommunications or signal processing applications. These Transoners transmit electrical signals, with step-down voltage transformation, from an input terminal to an output terminal, while providing electrical isolation between the input and output terminals. Over very wide frequency bandwidths, Wide Band Transoners exhibit a constant but low level of voltage gain, defined as the ratio of voltage at the output terminal to voltage at the input terminal. They also exhibit high DC input and output impedance.

Since different models of Wide Band Transoners exhibit performance advantages in different frequency ranges, this type of Transoner is divided into three categories: Audio Frequency, Voice & Data and High Frequency. These categories correspond to anticipated applications or product groupings.

POWER Transoner

The second distinct mode of operation is power transformation. Operating at resonance, Transoners exhibit high voltage gain and significant power transfer. Useful for power conversion and power switching, these Power Transoners can be designed to be either isolating or non-isolating. Both types are capable of efficiently stepping up the voltage of an AC signal applied to the device’s input terminal and producing a sinusoidal output signal. Although Power Transoners are very small, they have exceptionally high power ratings, especially as compared to conventional wire-wound transformers of similar size. Relative to other piezoelectric transformers that are commercially available, the power rating of a typical Power Transoner is approximately an order of magnitude greater. Power Transoners can be designed to operate efficiently at virtually any input frequency between 1 kHz and 250 kHz (demonstrated range). Individual devices, however, have relatively narrow operational frequency bandwidths, meaning a particular Power Transoner should be matched with the operational frequency of its intended application or load.

Isolating Power Transoners transmit electrical signals, with step-up voltage transformation, from an input terminal to an output terminal, while providing electrical isolation between input and output terminals. These devices can provide voltage gains in the range of 1:0.25 to 1:18; further research and development should result in isolating Power Transoners having voltage gains of up to 1:100. Such devices appear particularly well suited for applications requiring electrically isolated power transmission and/or requiring voltage conversion of an AC signal, such as in computers, medical equipment and certain lighting systems.

Non-isolating Power Transoners are much like isolating devices in that they are very small and highly efficient, but they do not provide electrical isolation. Non-isolating Power Transoners are well suited for compact applications that require high voltage gain at fixed frequencies but do not require electrical isolation. These applications include electro-luminescent displays, fluorescent lights, HID lamps, flash camera lights, miniature lights, and certain power supplies.
