The Key to Superior Charger Quality: AFV-P series Programmable AC Power Source

2024/09/05

Navigating the Global Fast-Charging Market


As the demand for high-performance electronic devices soars, the wall charger market is undergoing a rapid transformation. The introduction of standards like USB PD3.1 has significantly increased power requirements, pushing chargers to deliver up to 240W. To meet these demands, manufacturers are leveraging cutting-edge technologies like Gallium Nitride (GaN) and Silicon Carbide (SiC). However, these technologies also demand greater performance and safety standards. Ensuring that chargers operate reliably across various conditions is a critical challenge for manufacturers.

AFV-P series Programmable AC Power Source: The Indispensable Partner for Charger Testing



In today's competitive market, rigorous testing is essential to deliver exceptional charging products, and the AFV-P series is the perfect solution. This series significantly enhances testing precision and efficiency across several applications:

∎ Input Voltage Testing

Chargers need to operate in various power grid environments worldwide, which requires them to adapt to a wide range of input voltages. The AFV-P series can simulate an input voltage range from 90V to 264V and supports frequency settings from 45Hz to 65Hz, covering the major global power grid standards. By setting specific input voltages and frequencies, AFV-P can easily perform various input voltage stability tests to ensure that chargers operate reliably under different grid conditions.



∎ Conversion Efficiency Testing

The conversion efficiency of chargers is a critical performance indicator that affects products’energy savings and heat dissipation. AFV-P series can output power at 220V/110V with frequencies of 50Hz/60Hz, to verify if the charger could output 5V, 9V, 12V, 15V, and 20V. The input and output power under different conditions can be measured, by connecting a DC electronic load and a power meter with AFV-P, then users can calculate whether the conversion efficiency meets relevant energy efficiency standards, such as CoC V5 and GB 20943.

∎ Inrush Current Testing



Inrush current testing is a critical aspect of charger performance. The AFV-P series enables precise simulation of inrush currents under various conditions by allowing users to set a starting angle between 0 and 359 degrees. By initiating the charger at a 90-degree starting angle, the AFV-P facilitates rigorous testing of charger safety and reliability, ensuring compliance with relevant standards.

∎ Power Line Disturbance



To simulate power line disturbance of the power grid, AFV-P series supports ramp, step, and transient simulation for voltage and frequency disturbance tests, as well as short interruption and voltage spike tests. AFV-P series can rapidly switch voltage from 90V to 264V and frequency from 45Hz to 65Hz, validating the charger's response speed and stability during voltage spikes and dips, ensuring it can handle complex power grid conditions.

Boost Your Product Competitiveness with AFV-P series

With the increasingly complex demands in the charger market, AFV-P series programmable AC power source offers manufacturers strong technical support through exceptional performance and flexible testing solutions. With various voltage/frequency settings, power stability, and power line disturbance simulation, AFV-P series provides precise and efficient testing solutions, assisting customers in enhancing product quality and reliability during development and production.
