Evaluation and Demonstration Boards and Kits

The APEK3979SLP-01-T-DK Evaluation Board is a high power factor, high efficiency, and low standby power, optimized for commercial and industrial applications. It integrates both primary and secondary channels into a single integrated power factor controller. It is designed to achieve superior performance without sacrificing flexibility.

The APEK3979SLP-01-T-DK Evaluation Board includes a primary channel and secondary channel for primary switching and pulse frequency modulation respectively. The primary channel of the board utilizes pulse width modulation (PWM) to generate an output with higher power factor and efficiency. The PWM signal is guided by the programmable internal oscillator which can be set to generate the desired frequency of operation or pulse width.

The secondary channel of the APEK3979SLP-01-T-DK includes two isolated flyback converters for the high voltage and low voltage power requirements. These converters may be configured to provide single or multiple output voltage levels depending on the system requirements. The board also includes two digital-to-analog converters (DACs) and four analog-to-digital converters (ADCs) to monitor the input voltage, output voltage, and current, and to generate output PWM signals. The primary and secondary channels can be configured for either standard or parallel configuration, depending on the system requirements.

The APEK3979SLP-01-T-DK can be used in a wide range of applications, including AC-to-AC and AC-to-DC power conversion, TV and home audio systems, and industrial controllers. The board has been designed to achieve high efficiency and low standby power while operating in a wide range of temperature and input voltage. The board can also be used to evaluate the efficiency of AC-to-DC linear topologies and to verify the performance of various AC-to-DC and DC-to-DC power conversion schemes.

The working principle of the APEK3979SLP-01-T-DK Evaluation Board is based on the principle of pulse-width modulation (PWM). The output voltage is generated by modulating the duty cycle or pulse width of the switching signal according to the value of the input voltage. The board includes a control circuit, which produces an output PWM signal based on the input voltage. The output PWM signal is then applied to the gate of the switch in the primary channel. By varying the pulse width of the switching signal, the output voltage of the primary channel can be regulated accordingly.

The APEK3979SLP-01-T-DK Evaluation Board is a flexible and efficient solution for power factor optimized AC-to-DC and DC-to-DC power conversion. It integrates primary and secondary channels in a single integrated power factor controller and offers adjustable output voltage, high efficiency, and low standby power. Furthermore, the board can be used to evaluate the performance of various AC-to-DC and DC-to-DC topologies, and to determine the most efficient and cost-effective power conversion solutions for a range of applications.
