Core Fundamental Functions
Voltage Conversion: Steps voltage up or down-for example, converting high-voltage battery power in new energy vehicles into the lower voltage required for onboard equipment.
AC/DC Conversion: Converts grid alternating current (AC) into the direct current (DC) required by devices, or inverts battery DC into AC to power AC appliances.
Voltage Regulation and Electrical Isolation:Maintains a stable output voltage despite input fluctuations and provides electrical isolation (often via an isolation transformer) to prevent electric shock and ensure safety.
Waveform and Frequency Adjustment:Converts 50Hz mains power to 60Hz AC and adjusts output waveforms to meet the specific power requirements of various specialized devices.
Specialized Functions by Type
AC-DC Converters: Commonly found in mobile phone chargers and laptop power adapters; they convert 220V grid AC into the low-voltage DC required by electronic devices.
DC-DC Converters: Widely used in consumer electronics and new energy vehicles to flexibly convert between different DC voltage levels; they offer efficiencies of 85%–95% and support bidirectional energy transfer.
Inverters (DC-AC): Core components in solar power systems and vehicle power supplies; they convert DC from photovoltaic panels or batteries into standard household AC to power AC appliances.
