A single-phase AC power supply with programmable voltage is a power supply device capable of converting a constant single-phase AC voltage into a variable AC voltage. Its core components include rectifiers, filters, inverters, and controllers. The rectifier converts the input AC voltage into DC voltage, the filter smooths the rectified DC voltage, and the inverter converts the smoothed DC voltage into a variable AC voltage, and finally the controller controls and adjusts the whole system. In addition, the working principle of this power supply is mainly based on PWM technology. When the input power supply is stepped down to the required voltage of the power supply through the transformer, it is controlled by the circuit to generate a PWM modulation signal. By controlling the duty cycle of the PWM modulation, the output voltage can be precisely regulated. At the same time, the PWM modulation signal can also control the opening and closing of the protection circuit and the working state of the power supply itself, so as to ensure the stability and reliability of the power supply.
1.Wide output range: The programmable single-phase AC power supply has a wide output range to meet different current and voltage requirements. The user can program the output parameters to achieve current output from milliampere level to hundreds of amps, and voltage output from a few volts to hundreds of volts, which is very flexible.
2.High precision: The output accuracy of the programmable single-phase AC power supply is very high, capable of reaching an accuracy of a few percent. This is very important for some precision experiments and applications that require high current and voltage.
3.Waveform programmable: The programmable single-phase AC power supply has the function of waveform adjustment, which can realize the output of various waveforms such as sine wave, square wave, and triangle wave according to needs. This is very useful in the fields of power testing, electronic device testing, etc.
4.A variety of protection functions: The programmable single-phase AC power supply has a variety of protection functions, such as overload protection, overtemperature protection, overvoltage protection, etc., which can effectively protect the equipment and improve the stability of the system.
