About China AC-DC Power Supply factory
An AC-DC power source is a power source that converts alternating current from the grid into the direct current needed to power most electronic devices. From transportation and industrial markets to consumer and IoT applications, AC-DC power supplies are integral components in the systems that make the world go round.
Why don’t households use direct current?
Direct current is not used in the home because for the same voltage value, direct current is more lethal than alternating current because direct current does not pass through zero. Electrolytic corrosion is more of a problem with direct current. DC inductors are more complicated. It requires commutators, electronic switches and brushes.
It is advisable to avoid any form of electric shock, but in these cases, direct current is considered safer because the body’s threshold for direct current is much higher than its threshold for alternating current.
