AC/DC converters are widely used in industrial, consumer, automotive, medical, and commercial applications. They convert alternating current (AC) to direct current (DC) for the transfer of energy or an electrical signal to a device. AC/DC converters are generally more efficient than using transformers for AC power conversion and DC/AC inverter applications. The LDA300W-30-CT is an AC/DC converter designed to cost-effectively and efficiently meet the requirements of low power applications. This product is a multi-phase, wide input voltage range, isolated AC-DC converter and provides output power up to 300W. The LDA300W-30-CT offers a number of features including wide input voltage range from 15-450VAC, universal input, high efficiency up to 94%, low total harmonic distortion (THD) of less than 10%, active input current harmonic, intelligent remote gating, and over-temperature protection. It also has a wide temperature range of -40 to +85°C, remote ON/OFF control and a small footprint with a high power density. The working principle of the LDA300W-30-CT AC/DC converter is based on pulse-width modulation (PWM) topology. It takes the AC input, rectifies it, and then filters the rectified voltage. The rectified and filtered voltage is then chopped into a square wave by comparing it to the PWM reference and output at the required required output voltage. The LDA300W-30-CT also uses a special technique known as phase-shifted zero-current-detection to optimise the design of the power stage, thus allowing for wide input range, low total harmonic distortion, and high efficiency. The phase-shifted zero-current-detection technique can detect the zero-current-crossing of both the input current and output current.The LDA300W-30-CT is suitable for use in many applications including ITE, LED lighting, industrial automation, telecommunications, laboratory equipment, motor control, and medical applications.The LDA300W-30-CT demonstrates high power density, high efficiency, low output ripple and noise, and low temperatures and no external components, making it an ideal solution for low power applications.In short, the LDA300W-30-CT is an AC/DC converter designed to cost-effectively and efficiently convert AC to DC power. It is based on pulse-width modulation (PWM) topology and uses a phase-shifted zero-current-detection technique to optimise its design. The LDA300W-30-CT is suitable for use in many low power applications including ITE, LED lighting, industrial automation, telecommunications, laboratory equipment, motor control, and medical applications.
