AC and DC Linear Power Supplies are also known as series power supplies. In a AC and DC Linear Power Supply, a transformer consisting of an iron core and coil is used to reduce the voltage to an incoming alternating current (AC).
The voltage is then rectified by a diode in the rectifier circuit and smoothed by a capacitor in the smoothing circuit to provide a stable voltage.
The voltage output from the rectifier circuit is a series of positive peaks of a sine wave, which is not a suitable stable current. Therefore, the voltage is leveled using a smoothing circuit consisting of a capacitor, and a stabilizing circuit (control circuit).
There are two types of control circuits: shunts and series circuits. Both methods monitor and control the output DC voltage to maintain a constant value. The difference between the input and output voltages generates heat; therefore, a large heat sink is required.
An AC and DC Linear Power Supply requires a dedicated AC transformer based on input voltage, output voltage, and power.
Therefore, each device had a fixed capacity and required a power supply with a dedicated transformer for each application. Both linear and switching power supplies provide a stable direct current (also abbreviated as “direct current” or “DC”).
DC is used in the circuits of most electronic devices, such as smartphones, computers, air conditioners, and factory robots. Because each type of device and internal circuit of such electronic equipment require different voltages, a direct current source appropriate for each voltage is necessary.
The Global AC and DC Linear Power Supplies Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
KEYSIGHT EDU36311A Smart Bench Essentials AC and DC Linear Power Supplies – The Keysight Smart Bench Essentials (SBE) Series is a set of four unique instruments with PathWave BenchVue application software to connect, control, and capture measurement data.
The EDU36311A triple-output power supply has a compact design to fit anywhere on your bench. Monitor all the outputs simultaneously from any angle with its 7-inch color display.
Each output is independent — connect your outputs in a series for higher voltage, in parallel for additional current, or stack to provide 0 to ±30 V. A sequencing feature enables and disables outputs in a set pattern. You can now activate the control logic before applying power to the rest of your device.
