Evaluation boards are an essential tool used by engineers, researchers and academics to demonstrate, test and develop new solutions. Their use is particularly important in the development of DC/DC and AC/DC switched mode power supplies (SMPSs), due to the complicated and highly dynamic nature of their operation. One such evaluation board available is the TMDSC2KWRKSHPKIT, which is designed to assist engineers in the development of SMPSs. This article will discuss the application fields and working principle of the TMDSC2KWRKSHPKIT.

The TMDSC2KWRKSHPKIT is designed to allow engineers to rapidly evaluate their designs and accurately predict the expected performance for the system in terms of both transient response and output power capability. Utilising a dual mode converter with a built-in dynamic response evaluation circuit, the evaluation board is suitable for use in a variety of applications, including AC/DC offline SMPSs, low power DC/DC converters, high power resonant converters, wide input voltage range applications and current-mode line regulation designs.

The working principles of the TMDSC2KWRKSHPKIT are based on the use of a Dual Mode Control Technique (DMCT). This technique aims to provide the engineer with improved control over the converter by using two distinct control loops, a first inner loop and a second outer loop. The first inner control loop utilises a current mode controlled oscillator on the primary side of the converter. The output frequency of the oscillator is determined by the proportional relationship between the voltage of the input capacitor and the feedback of the regulating circuit.

The second outer control loop uses a voltage mode controller on the secondary side of the converter. This control loop compensates for the variations in the output voltage due to load changes or input voltage fluctuations. By utilising the two control loops in tandem, the engineers have the ability to design highly efficient converters, control the output over a wider range and achieve faster transient response times.

The TMDSC2KWRKSHPKIT also offers a variety of other features, including a power supply track, library modules for different components and industry-standard evaluation software compatible with Windows, Mac OS and Linux operating systems. The evaluation board is CE-registered, RoHS compliant and offers a wide operating temperature range of -40°C to +65°C.

In conclusion, the TMDSC2KWRKSHPKIT evaluation board is an effective tool for engineers who are looking to develop DC/DC and AC/DC switched mode power supplies. The board’s dual mode control technique and additional features are designed to assist in the development of efficient converters, with faster transient response times and wider output voltage control.
