CVCF (Frequency Converter)

Constant Voltage Constant Frequency (CVCF) System. Simulates global grid conditions to operate or test electronics destined for USA (60Hz), Europe (50Hz), or Aviation (400Hz).

What It Does

Electrical standards differ globally. India uses 50Hz, while the USA and Saudi Arabia use 60Hz. Aircraft and Radar systems use 400Hz.

A **CVCF Converter** completely decouples the output from the input. It takes unstable, fluctuating grid power (any frequency) and generates a **pure sine wave** at a fixed Voltage and fixed Frequency. It acts as an infinite, perfect power source for testing labs.

Double Conversion Process

It works like a precision power plant in a box:

1. Rectification (AC → DC): The incoming mains (which may have dirty harmonics or wrong frequency) is converted to stable DC.
2. Bus Regulation: The DC bus voltage is filtered and regulated.
3. Inversion (DC → AC): The IGBT Inverter reconstructs a new AC sine wave. Unlike a transformer, the frequency is synthesized digitally, so 50Hz in can become 60Hz out.
4. Isolation: An output isolation transformer ensures the load is galvanically separated from the utility grid.

Key Features

400Hz Capability

Essential for testing avionics, radar, and military equipment on the ground.

Export Testing

Test your 60Hz machines (intended for USA export) right here in India.

Clean Power

Total Harmonic Distortion (THD) is less than 3%, ideal for lab instruments.

Adjustable Output

Some models allow variable frequency (45Hz - 400Hz) for R&D stress testing.
