This is a dedicated evaluation board using emitter switched bipolar transistors (ESBTs) featuring the high-power, wide input range requirement of the highly demanding industrial market. The maximum output power is 100 W. The need to handle both high output power and wide input voltage leads to the design of a flyback topology. The flyback converter is a popular choice in applications where the required power is normally less than 200 W. The main reasons for its popularity are its simplicity, low cost and high efficiency despite a small number of active components. This evaluation board provides a solution for a power supply solution for 3-phase applications such as inverters for induction motors, welding machines, and UPS.
The STEVAL-ISA015V2 is a dedicated evaluation board designed for 3-phase power supply applications. It utilizes emitter-switched bipolar transistors (ESBTs) to meet high-power and wide input range requirements typical of the industrial market. The board employs a flyback topology to handle up to 100 W of output power.
