AC/DC converters are electric devices that convert alternating current (AC) to direct current (DC). The PBA300F-15 is an AC-DC high-efficiency, low power, low-noise, and high power converter. It is primarily used for powering LED lights, electric vehicles, and other industrial applications.

Application Field

The PBA300F-15 is suitable for LED lighting, electric vehicle charging, LED TV backlights, charger products, mobile phone chargers, DC motors, and other industrial applications where high efficiency and low power consumption are needed. The wide input voltage range of 88~305VAC and high peak LLC resonance frequency make it suitable for universal applications.

The design of the PBA300F-15 converter with built-in active PFC and full-protection features make it an excellent choice for LED lighting and other high efficiency applications.

Working principle

The PBA300F-15 utilizes a full-bridge zero-voltage switching (ZVS) resonant converter topology based on a high frequency LLC resonant converter. It provides high efficiency with low noise and low power consumption. The power factor correction (PFC) feature enables high efficiency performance, which meets the DOE VI standard.

The LLC resonant converter has two stages: the PFC pre-regulator stage and the LLC stage. The PFC pre-regulator stage boosts the incoming AC line up to a voltage level suitable for the LLC resonant converter. The LLC stage is responsible for producing the desired output DC voltage from the PFC boosted voltage. The LLC resonant frequency is set at a high frequency such as 260kHz, allowing the converter to achieve high efficiency and low power consumption while maintaining low-noise operation. The PBA300F-15 also employs advanced control algorithms to regulate the power output and ensure high efficiency performance.

The device also comes with robust protection features that protect the converter from over-voltage, over-current, and Under-voltage situations. The device is fully RoHS compliant and is suitable for Class A EMI/EMC standards.

In summary, the PBA300F-15 AC-DC converter provides a high-efficiency power solution suitable for LED lighting and other high-efficiency applications. Its wide input voltage range and high peak LLC resonance frequency make it an ideal choice for universal applications, while its low noise and low power consumption make it suitable for low power applications as well. The built-in active PFC and full-protection features make it an excellent choice for LED lighting and other high efficiency applications.
