With its turnkey solution, the KITPF3000FRDMEVM evaluation board is capable of providing an efficient and cost-effective power solution for a variety of applications.

The working principle behind the KITPF3000FRDMEVM evaluation board is based on the principles of Power Factor Correction (PFC). PFC is a method used to reduce power consumption and limit the amount of power drawn from the mains. The FAN3000F PFC controller utilizes a synchronous rectifier to employ a power conversion topology that is capable of providing an efficient, almost perfect power factor operation. This method reduces the amount of current drawn from the AC source, resulting in lower power bills and improved system reliability.

The circuit of the KITPF3000FRDMEVM evaluation board includes three main components: the PFC controller, the input EMI filter, and the output transformer. The FAN3000F controller uses an avenue control method to provide a pulse-width modulated (PWM) signal to the gate driver. This signal controls the switching of the input MOSFETs, providing an efficient PFC operation with a low total harmonic distortion. The input EMI filter, which is included in the circuit, is designed to reduce the amount of noise that is generated by the switching of the MOSFETs, and the output transformer is used to step down the voltage as necessary.

The adjustable DC output voltage of the KITPF3000FRDMEVM evaluation board enables the user to tailor the power output for different applications. The adjustable output voltage is achieved by using the high power capacity of the FAN3000F controller’s integrated over-voltage and under-voltage protection. Furthermore, the FAN3000F controller features a Power Factor Correction (PFC) mode with an adjustable frequency and duty cycle output, making it suitable for a wide range of AC input sources.

In summary, the KITPF3000FRDMEVM evaluation board is a turnkey solution for evaluating the performance of the Fairchild Semi’s FAN3000F off-line PFC controller. The board is capable of providing an efficient and cost-effective power solution for a variety of applications, and its control board features adjustable output voltage and power factor correction. Utilizing the features of the FAN3000F PFC controller, the KITPF3000FRDMEVM board is an ideal solution for applications such as consumer electronics, medical diagnostics, lighting ballasts, and telecommunications systems.
