AC to DC Converters are electrical devices used to convert alternating current (AC) into direct current (DC). AC to DC Converters are available in a variety of forms, including simple rectifier diodes, bridge rectifiers, thyristors, and switching power supplies. The DLP75241 AC to DC converter is an integrated, low cost power supply solution, designed to deliver efficient, reliable power from a single phase 220VAC input. The integrated design helps reduce development time, ensuring the end product reaches market faster and ensures greater product reliability and lifetime.

Description of Application Field and Working Principle of DLP75241

The DLP75241 is a single phase, high performance AC to DC converter. It is designed to provide a regulated DC output voltage from a single-phase 220V AC power source. The device has integrated over-voltage, over-current, and short-circuit protection to ensure reliable operation. The output range is adjustable from 24V to 48V. The device is capable of supplying up to 100W of power. The wide input AC range allows the converter to be used in a variety of applications including medical, industrial, and consumer.

The functional block diagram of DLP75241 is shown below. The device consists of an AC/DC converter, AC EMI filter, and a DC/DC converter. The AC input is rectified by the full bridge rectifier circuit. The bridge rectifier converts the AC input voltage to a pulsating DC voltage. The AC EMI filter is then used to reduce noise and ripple from the input. The DC line voltage is then switched by the integrated high-frequency inverter circuit to generate the DC output voltage. The DC output voltage is regulated and equalized by the integrated constant voltage oscillator. The integrated control and protection circuitry provides current and power limiting protection, as well as under-voltage and over-voltage shutdown.

The AC/DC converter and DC/DC converter section of the DLP75241 allow the device to be used in applications requiring non-isolated power supplies. The power conversion efficiency of the device is up to 93%. The high efficiency of the device ensures low heat dissipation, reducing the size of the device. The device also has a wide operating temperature range of -40°C to +85°C, allowing the device to be used in harsh working environments.

The DLP75241 is an ideal solution for applications requiring a reliable, cost-efficient, and space-saving power supply. The device is suitable for applications such as Uninterruptible Power Supplies (UPS), medical equipment, industrial machinery, consumer appliances, and telecom systems. The device is certified to meet international safety standards such as IEC 60950-1, and is available in a variety of cost-effective packages.
