AC-to-DC Solutions
AC-DC converters are electrical circuits that transform alternating current (AC) input into direct current (DC) output. They are used in power electronic applications where the power input a 50 Hz or 60 Hz sine-wave AC voltage that requires power conversion for a DC output. AC to DC converters use rectifiers to turn AC input into DC output, regulators to adjust the voltage level, and capacitors to smooth the pulsating DC. AC-DC converters can have more than one output and may feature like overcurrent, overvoltage, or short circuit protection. Some switching converters feature active or passive power factor correction to counteract the distortion and raise the power factor.
However, many AC/DC converters use more sophisticated, multi-stage conversion topologies. Rectifiers are implemented using semiconductor devices that conditionally conduct current in one direction only, like diodes. More sophisticated semiconductor rectifiers include thyristors. Silicon controlled rectifiers (SCR) and triode for alternating current (TRIAC) are analogous to a relay in that a small amount of voltage can control the flow of a larger voltage and current.
AC-DC converters are used in computers, televisions, cell phone chargers, and other electronic consumer devices. They are also used in medical, military, and telecommunications equipment; kitchen appliances; industrial machinery; and commercial products that use DC motors.
