CVCF (Constant Voltage Constant Frequency) power supply provides stable output voltage and frequency regardless of load or input variations.

• ✔ Output: Fixed voltage & frequency (e.g., 220VAC, 50Hz or 110VAC, 60Hz)
• ✔ Typically used in UPS systems, inverters, and precision equipment
• ✔ Achieved via DC-AC inverter with feedback control (SPWM + regulator)
• ✔ Common topologies: Full-bridge inverter with LC filter
• ✔ Control ICs: SG3525, TMS320F28xx, or dedicated digital controllers

Note: Requires stable DC input (battery or rectified source) and precise regulation loop.
