ATO DC-DC Converter, was established in 2009 as a manufacturer of DC-DC Boost Buck Converters, Power Sources products and Engineering Services. ATO DC-DC converter is a circuit or electromechanical device that converts electrical energy, which can convert a direct current (DC) power source into a direct current (approximately DC or DC) power supply in different voltages. Its power can range from very small (small batteries) to very large (high voltage power conversion). The DC-DC converter is to repeat the on-off switch, convert the DC voltage or current into a high-frequency square wave voltage or current, and then rectify and smooth it into a DC voltage output. At present, ATO DC-DC converters are widely used in power conversion systems for electric vehicles, such as electric vehicles, electric cleaning vehicles, and electric motorcycles.
