AC DC Converters

HAD12-0.4-AG is a prototype AC/DC converter (ACDC) developed by the research department at Wrengel Corporation. The product uses solid state transistor switching technology (SSTT) to connect both AC and DC sources in parallel and create a simple power transfer from one to the other. The versatility of the converter makes it suitable for a wide range of applications from power supplies and power converters to automotive systems, aircraft, marine and industrial equipment.

Product Overview

HAD12-0.4-AG AC/DC converter is based on the acoustic resonance principle and uses SSTT technology. The main features of the converter include: a power rating of 0.4kW, a standby power consumption of 12W, an input voltage range of 90-240VAC, and an output voltage range of 10-48V DC. The product\'s size is also relatively small, being just 165mm x 163mm x 200mm, making it easy to install in almost any environment. In addition, the converter features three adjustment knobs that are easily accessible and allow users to adjust the output current and voltage without opening the casing.

Application Field

HAD12-0.4-AG AC/DC converter is ideally suited for a range of applications such as providing power backup in the event of power outage, in industrial and transportation equipment, such as locomotives, buses and emergency vehicles, as well as in buildings and factories for power distribution and protection purposes. The product is also suitable for use in renewable energy systems, such as solar, wind or hydro power systems, where its reliability and small size make it an ideal choice. In addition, the HAD12-0.4-AG can be used in security systems and medical equipment.

Working Principle

The working principle of the HAD12-0.4-AG converter is based on a rugged disc resonator, which acts like an acoustic transformer to convert AC to DC without the need for complicated transformers or bulky power supplies. The product includes four switchable channels: the power resonance channel for power conversion, the standby channel, the feedback channel, and the cold-start channel.The power resonator is used to convert AC to DC, with the power being passed through a transistor-based rectifier stage. The resulting DC is then routed to an output voltage control stage, which is where the user can adjust the desired output voltage. The standby channel is used to enable start-up and shut-down, as well as protect the converter from power outages. The feedback channel is used for monitoring the output voltage, and provides feedback to the control circuitry to ensure the output remains stable. Finally, the cold-start channel is used to protect the device from failures caused by cold temperature.

Conclusion

The HAD12-0.4-AG is an advanced AC/DC converter that uses SSTT technology and a disc resonator to efficiently convert AC to DC without the need for bulky power supplies. The product is suitable for a range of applications, from power backup solutions and renewable energy systems to industrial and transportation equipment. The product is also equipped with three adjustable knobs to tweak the output current and voltage according to user preference. The working principle of the HAD12-0.4-AG is based on the disc resonator, which helps convert AC to DC, while the standby channel is used to protect the device from power outages. Finally, the feedback channel provides feedback to the control circuitry to ensure the desired output is maintained.
