The ADA750F-36 AC/DC Converter is a high-efficiency non-isolated surface-mount, open-frame power supply module that can be used in a variety of industrial, medical, telecommunications, transportation, and energy management applications. The ADA750F-36 is designed to take a wide rangeinput AC voltage and provide a regulated, isolated, and regulated DC output. The power module features a wide operating input voltage range of 84 to 264 Vac, and is rated for continuous operation up to 750 watts.

The ADA750F-36 can deliver up to 36V of regulated DC output. It can be configured for variable voltage or current modes. The converters feature an internal active factor correction (AFC) circuit, providing high power factor and total harmonic distortion (THD) of less than 5% at 100 VAC input. The module also has an active power control circuit that automatically reduces power dissipation as the output load current decreases.

The ADA750F-36 offers a variety of features designed to make integration and commissioning easier. It has built-in self-protection against over-voltage, over-current, short-circuit, and overtemperature conditions. It also includes an adjustable remote sense, adjustable standby control, and an inhibit function, all of which can be controlled externally. The module features an isolated open-frame construction with a ruggedized plastic housing for mounting in harsh environments.

The ADA750F-36 also includes a robust power circuit design with a high-frequency switched-mode PWM converter. Output ripple is minimized with state-of-the-art interleaving and a high-efficiency active interleaver. Comprehensive protection is also provided via built-in fault protection features, such as output overvoltage and overcurrent protection.

The working principle of the ADA750F-36 AC/DC Converter is fairly simple and straightforward. It converts the AC input voltage to a high frequency (typically 200 kHz to 500 kHz) DC voltage using a high frequency transformer. This high frequency DC voltage is then rectified and controlled by a switching circuit. The control circuit utilizes a pulse-width modulation (PWM) technique to regulate the DC output voltage and maintain the required level of load current.

The main function of the ADA750F-36 is to provide a regulated DC output voltage. The high frequency transformer is used to transfer energy from the AC input to the DC output, eliminating the need for bulky and expensive transformers. The transformer also helps reduce the output ripple, providing a more stable DC output voltage. The PWM technique used in the control circuit helps maintain a constant output voltage even during light and medium load conditions. The module is designed to operate with very little noise and minimal heat dissipation, making it well suited for many industrial, medical, and telecommunications applications.
