Manufacturer, Supplier and Exporter of Three 3 Phase Static Voltage Stabilizers / Three Phase Static Voltage Regulators
VEPL's Ultra Fast Series Static voltage stabilizer is an automatic voltage regulator characterized by its absence of moving parts. Unlike traditional systems, this static voltage stabilizer employs advanced technology for rapid voltage regulation, utilizing a 16-bit microcontroller and digital signal processing. It achieves stabilization based on true RMS voltage, and its output voltage remains unaffected by variations in load power factor (cos∅) or load percentage, ranging from 0% to 100% on each phase.
The core components of this static voltage stabilizer include a buck-boost transformer, a conversion unit, and IGBT (Static Switches). Voltage compensation on the primary winding of the buck-boost transformer is executed by a DSP-based PWM control electronic board through IGBT modules. Instead of the conventional auto transformer, this control circuit performs voltage adjustments by adding or subtracting voltages, swiftly compensating for fluctuations in the mains voltage within an impressive response time of just 20 milliseconds.
One of the primary advantages of this static voltage stabilizer is its lack of moving parts, which eliminates the need for maintenance over time. In contrast, traditional servo motor voltage regulators contain various mechanical components like motors, gear trains, dead-end limit switches, variable transformer carbon brushes, and rotating wires. These moving parts wear down with prolonged use, and dust accumulation can lead to faults. Additionally, when such machines operate continuously under load, auto transformer surfaces may overheat and wear, potentially causing voltage interruptions.
In summary, static voltage stabilizers, such as the VEPL Ultra Fast Series, offer reliable and long-term operation due to their electronic, non-mechanical regulation performed at ultrafast speeds. These stabilizers ensure the continuous supply of clean and stable power, guaranteeing the seamless operation of electronic devices and machinery. This is achieved through precise pulse width modulation (PWM) switching of a buck-boost transformer via a converter-inverter driven by high-frequency Insulated Gate Bipolar Transistors (IGBTs). The system measures incoming AC power against the nominal voltage and rapidly adjusts it, up to 20,000 times per second, to correct voltage disturbances, sags, or swells, all within a remarkable 20- millisecond timeframe. This ensures that all voltage irregularities fall within the ITIC curve, guaranteeing flawless operation of electronic equipment.
