AC DC Converters: IRM-45-15ST Application Field and Working PrincipleThe IRM-45-15ST, manufactured by International Rectifier, is an AC DC (Alternating Current to Direct Current) converter. It is a three terminal, 35Amp, 400V, high frequency converter designed to regulate the output voltage steady at 45V DC. This AC DC converter is used in a variety of applications, including switch-mode power supplies, AC motor drives, welding systems, and frequency converters.The IRM-45-15ST is a flyback converter topology, in which a transformer is used for energy storage and isolation. This topology is generally used in any system in which power is required from an AC bus to a DC load, as well as in AC to AC conversion, AC to DC conversion, or DC to DC conversion. In this configuration, the polyphase rectifier bridge of the AC bus supplies an electric current that is converted to unidirectional AC by an auxiliary diode bridge. This AC voltage is then fed into a transformer, which boosts the voltage so it can be rectified into a high-voltage DC and delivered to the load.In operation, the flyback converter of the IRM-45-15ST works by first rectifying an AC input voltage to generate a high voltage DC. An output voltage is then generated by feeding this high voltage DC current through an inductor or transformer, where it is current-limited and the voltage is then stepped-down. The output voltage is then stabilized and returned to the load. The flyback control feedback is controlled with current and voltage sensors which detect the load current and output voltage. The controllers of the IRM-45-15ST then continuously regulate the output voltage relative to the load voltage, and the output current and voltage are also continuously monitored.The IRM-45-15ST converter has a number of unique features that make it attractive for a variety of applications. This AC DC converter offers an output power of up to 400W, making it suitable for larger loads and applications where a high current draw is needed. It also has a high power conversion efficiency, making it one of the most efficient converters on the market. Additionally, the IRM-45-15ST features built-in protection circuits, such as over-temperature, over-current, and short-circuit protection, which helps ensure the safety of the converter and the load.The IRM-45-15ST is well-suited for applications that require efficient, reliable power conversion and delivery in a small form factor. This converter is ideal for use in medical applications, in which power needs to be supplied to electronic medical instruments, as well as in telecommunications systems and industrial automation. Due to its excellent performance and reliability, the IRM-45-15ST has become popular in many applications that require a high power AC-DC converter.
