Primary switched-mode power supplies (PS8AES05WE) are widely used in a variety of applications, such as motor control and switching power converters. The special design of PS8AES05WE allows it to provide high efficiency, low noise, fast response, and low cost. In this article, we will discuss the application fields and working principle of PS8AES05WE.

Application Fields

The application fields of PS8AES05WE mainly include motor control, UPS systems and SMPS etc. Firstly, PS8AES05WE is generally used in motor control applications. It provides stable, reliable and efficient control over a wide range of rotor speed up to 8kW. The integrated intelligence and control module allow PS8AES05WE to precisely adjust the speed and torque of a particular motor in order to guarantee the motor operation with optimal performance. Secondly, PS8AES05WE is suitable for uninterruptible power supply (UPS) systems. It is able to sense the AC supply and precisely control the switching of loads between the main power supply and the UPS by monitoring the parameters, such as voltage and frequency. Lastly, PS8AES05WE is widely applied in switched-mode power supply ( SMPS ) systems. It can reduce the ripple factor and improve the efficiency by regulating the output voltage and current. The output voltage and current are precisely controlled to provide a clean, reliable and cost-effective power supply.

Working Principle

PS8AES05WE is a digitally-controlled switched-mode power supply. To understand its working principle, we need to overview the operating cycle. Generally, the operating cycle of a switched-mode power supply consists of four stages, which are input pre-charge, reset, regulation, and discharge. In the input pre-charge stage, the circuit performs pre-charging of the input capacitors to ensure proper operation when the input voltage is higher than the output voltage. During the reset stage, the circuit will reset the output voltage if the voltage level is insufficient. The regulation stage is then followed to control the output voltage, current and the output ripple waveform. Lastly, the discharge phase is initiated to discharge the output capacitor and protect the load from overvoltage.

In the regulation stage, PS8AES05WE utilizes current sourced Pulse-width Modulation (PWM) technique to control the power flow. The PWM waveform is used to switch the power switch On/Off to regulate the load voltage and current. The duty cycle of the PWM waveform is modulated according to the load voltage profile. The main components of the current source PWM architecture are a comparator, counter, charge pump and output power switch. The comparator will compare the reference voltage with the output voltage and generate an error signal that is used to adjust the counter and charge pump output. The counter is responsible for resetting the duty cycle with the change of the load voltage. The charge pump generates the drive signal for the power switch with the duty cycle set by the counter. The power switch will be toggled accordingly and regulate the load voltage and current.

Conclusion

In conclusion, PS8AES05WE is a cost-effective, efficient and reliable switched-mode power supply that is applicable to various applications, such as motor control and uninterruptible power supply. It utilizes the current sourced PWM architecture to precisely regulate the load voltage and current. With its advantages, PS8AES05WE is increasingly adopted for the replacement of traditional power supplies.
