The STEVAL-ISA094V1 evaluation board is mainly designed to be used as a versatile application tool with a wide range of applications. It is a perfect example of a off-line DC/DC & AC/DC (SMPS) that is used to convert low frequency alternating current (AC) to high-frequency alternating current (AC) and direct current (DC) as needed. This board is especially useful in those applications that require superior performance such as military, space and communications applications.
The STEVAL-ISA094V1 evaluation board is a low cost, low power and high performance evaluation board which is designed to clearly demonstrate the features of the patented low power-loss active-clamping flyback topology. This type of topology can be used to develop an offline 11 W flyback converter in an 8-to-2-4 package. It offers an extremely low no-load power consumption while having an excellent power factor that is greater than 0.95.
The STEVAL-ISA094V1 operates by taking mains voltage and converting it into a lower voltage with higher efficiency. This process is done with the usage of a two switches and one diode configuration, in combination with active-clamping circuitry and a frequency controlled flyback section. By incorporating high frequency transformers, low frequency AC input is converted into the higher frequency AC output. This output is then rectified by a bridge rectifier and the voltage is then regulated by the PWM circuit to make sure it remains stable at all times. This type of power supply enables a much higher efficiency which helps to reduce power loss and produce much less heat.
The STEVAL-ISA094V1 evaluation board is designed to enable users to measure all the parameters of the flyback topology more effectively and precisely. It consists of a power stage along with an evaluation board through which all the measurements can be tested and monitored. This board is specially designed to enable the user to evaluate different parameters associated with the active-clamping flyback topology while also allowing the user to test and compare efficiency, power factor and harmonic contents of the converter circuit. The evaluation board also incorporates all the necessary protections and interfaces that are crucial in ensuring its safety and durability.
In conclusion, the STEVAL-ISA094V1 evaluation board is an ideal choice for those looking for a highly efficient and durable DC/DC & AC/DC (Off-Line) SMPS. This board offers a wide range of applications while also providing a superior level of performance and safety. Its low-cost, low-power and high efficiency makes it the perfect choice for those who are looking to save money yet still get a high quality board. With its great features and advantages, the STEVAL-ISA094V1 evaluation board is an excellent choice for design engineers and power electronics experts.
