The PLA30F-15 AC DC Converters are high-power, fast-switching pulse width modulation (PWM) power converters, designed to treat AC power in order to be used by lower-power, DC-Based electronics. The PLA30F-15 AC DC Converters are capable of converting high AC voltages, up to 250Vrms (100 to 440Vrms for 15A), into a lower DC voltage.

When looking at the PLA30F-15 AC DC Converter’s construction, several important elements can be identified. The device contains both PWM and isolated, linear, switching buck stages. This structure allows for very fast transistor switching times (200kHz); furthermore, electromagnetic noise is reduced due to the integrated inductance. The addition of a MOSFET-based soft start circuit provides efficient ramp up of the device, while limiting in-rush current. To achieve high efficiency, the design of the PLA30F-15 has included a several cooling components, such as clips, bolts and other heat spreaders.

The PLA30F-15 features a wide range of working voltages, and offers tight load regulation. Models with output current ratings of up to 15.0A are available, with an adjustable output voltage range of 0.7 V to 45V. The device’s operating temperature range is -40°C to 85°C and has low power dissipation in active mode, allowing it to be used in a variety of applications, such as home appliances, computers and telecommunication systems.

The PLA30F-15 operates according to a principle of full-bridge PWM operation, using two pairs of insulated gate bipolar transistors (IGBTs); each transistor pair is operated in parallel, and each transistor pair has a different duty cycle. The switching frequency of the IGBTs is determined by an internal oscillator. The output of the PLA30F-15 is synchronous with the AC input voltage, allowing it to provide a controlled, stable voltage output, regardless of the fluctuations on the AC line. The device also employs a well-regulated frequency limiting switch-mode power-conversion circuit, which enables efficient power conversion under light load.

In addition to its significant power-conversion performance, the PLA30F-15 boasts high efficiency and low power dissipation, allowing it to be used in high-temperature operating environments. Furthermore, the power supply’s active power factor correction (PFC) circuit helps reduce harmonic content, and its integrated overvoltage and overcurrent protection circuits offer further protection to the device’s components.

The PLA30F-15 AC DC Converters are ideal for supplying low-voltage DC power in a wide variety of applications. Their high efficiency makes them suitable for use in a variety of consumer electronic products, and their small size makes them easy to integrate into existing systems. The device’s simple, robust construction ensures reliability and superior performance in a wide range of demanding applications.
