Solid State Frequency Converters
(also called "static", "electronic" or "AC Power Source")
Solid State units convert incoming AC Power into DC power (rectifier stage), and then convert the DC into the required AC Voltage and Frequency (inverter stage).
Typical Characteristics
- Suitable for use with Resistive, Capacitive, Inductive and Non-linear loads.
- Galvanic Isolation input to output. No Harmonic Distortion (EMI, EMC).
- Pure and Stable Sine wave Output.
- Sustained 300% Overload Capability.
- IGBT or MOSFET based, generating High Efficiency, Low Noise and Max. Reliability.
- Utilize PWM technology enhancing Compact Size, Light Weight.
- Equipped with Protection Circuits and Alarms.
Triathlon II Fully Adjustable Frequency Converter (T2FC Series)
Block Diagram
T2FC series AC Power Sources have the ability to simulate the AC voltage and frequency used in all countries. They are excellent instruments for R&D, design, production testing, and QA verification. The T2FC series delivers maximum rated power for any adjustable output voltage up to 300Vac (L-N) / 520Vac (L-L for 3 phase units), and at any adjustable frequency between 40Hz to 500 Hz.

Topology
6 Pulse or 12 Pulse Rectifier
Transformer
Inverter
The T3FC Frequency Converter system is composed of input breakers, input filter & protection network, rectifier, optional battery bank, inverter, isolation transformer, output filter and with IGBT/PWM technology. The basic topology is shown in the diagram above. Under normal AC, energy from the AC source is converted to DC power and supplied to the inverter, ready to support the output load with the exact frequency and voltage required.

Circuit Diagram
The T2FCP series units are Programmable AC Power Sources, and are GPIB (general purpose interface bus) instruments. The T2FCP units offer full programmability of voltage, frequency and phase angle for use as an Automatic Test System. Under GPIB control, the user has the ability to simulate surge and dropout, and to control the starting angle of AC output voltage. The T2FCP series AC Power Sources have 5 sets of memory for storing the commonly used test parameters for future use.
