AC/DC Power Supply
Also known as the main power supply, it converts AC to DC and DC to DC, obtaining a high DC voltage after energy is extracted from the grid and high-voltage rectification and filtering. The output of the DC/DC converter provides one or several stable DC voltages, with power ranging from a few watts to several thousand watts, suitable for various applications.
Direct Current/DC Power Supply
The secondary power supply, also known as the auxiliary power supply in communication systems, is provided by the main power source or a DC battery bank, delivering a direct current input voltage which, after DC/DC conversion, yields one or several DC voltages at the output.
Communication Power Supply
Communication power is supplied by DC/DC converters, but it is typically DC-48V or -24V power sources, with backup battery DC power as a backup, working voltage circuits, DC power voltage, generally divided into three types: central power supply grade, single board power supply, with the latter offering higher reliability.
(4) Modular Power Supply
High frequency, compact size, high reliability, easy installation, and great expandability make it increasingly popular. Currently, although the modules are produced in China, the high failure rate is due to the production technology not keeping up with international standards.36V Aviation Power Supply，400Hz Variable Frequency Power Supply，115/200V Power Supply，27V DC Power Supply，400 Hz power supply，Aviation Power Supply
Introduction to 7 Common DC/AC Power Sources
Power Supply by Inverter
An inverter power supply utilizes a thyristor circuit to convert direct current (DC) to alternating current (AC), corresponding to the reverse process of rectification, and is defined as an inverter power supply.
Inverter power supplies are widely used in various fields, including electricity, communication, industrial equipment, ships, solar energy, and wind power.
4. Variable Frequency Power Supply
An inverter power supply converts AC from the municipal power supply into AC and DC through alternating and direct conversion, outputting pure sine waves. The output frequency and voltage can be adjusted within a certain range. An inverter power supply is a variable-frequency device composed of an entire circuit including AC current, AC current, and a filter.
USB Uninterruptible Power Supply
The USB uninterrupted power supply is a system device that connects the battery to the host, converting DC power to commercial power through modules like the inverter circuit. It is mainly used to provide stable and uninterrupted power supply to single computers, computer network systems, or other power electronic devices such as solenoid valves, pressure transmitters, etc.
6. AC Voltage Stabilizer Power Supply
An AC stabilizer is a power supply that can provide a stable voltage and frequency. Most domestic manufacturers focus on stabilizing AC voltage.
7. Linear Stabilized Power Supply
Linear stabilizers share a common characteristic: their power devices operate in the linear region, stabilizing the output through voltage drops between the regulating devices. Due to the high static losses of the regulating devices, a large heat sink is required for cooling. Moreover, since the transformer operates at the industrial frequency (50Hz), it is relatively heavy.
