Power Transformer

Vritti Associates design and manufacture Power Transformers for a variety of power supply and power conversion applications. Power transformers may be designed in a wide variety of shapes and sizes.

Design requirements for a Power Transformer
Typical minimum requirements to be specified for a Power Transformer are

• Power rating in VA.
• Frequency usually 60 Hz.
• Number of primary windings.
• Number of secondary windings.
• Operating voltages levels.
• Operating current levels
• Operating frequency is needed for core calculations and wire sizing.
• Core material is selected for the known operating frequency or frequencies which is typically silicon steel laminations.
• Other Power transformer design considerations are space limitations and mounting technique.
• Lead terminations are also specified through the design of a Power Transformer.

Power transformer designs vary widely in terms of power rating, voltage and current levels (turns ratios), operating frequency, size, impedance, bandwidth (frequency response), winding and other parameters
