Core functions

Stable power supply: providing a continuous and reliable power supply for ABB excitation system, ensuring the normal operation of various functions of the excitation system, and ensuring the stability of power transmission and control.

Energy Conversion and Regulation: Accurately convert the input AC power into DC power suitable for the excitation system, and precisely adjust the output voltage and current to meet the energy requirements of the excitation system under different operating conditions.

Working principle

Input rectification: When the AC input voltage is connected to the module, it is first converted into DC power through the internal rectification circuit. This process utilizes the unidirectional conductivity of rectifying devices such as diodes to convert alternating positive and negative AC power into unidirectional DC power, providing a foundation for subsequent circuit processing.

Filtering and voltage stabilization: After rectification, the DC power often has certain fluctuations. At this time, the filtering circuit starts to work. Through a filtering network composed of components such as capacitors and inductors, the ripple in the DC power is removed, making it smoother and more stable. At the same time, the voltage regulator circuit monitors the output voltage in real time. When the voltage fluctuates, the circuit parameters are adjusted to ensure that the output voltage is always maintained at the set stable value.

Output adaptation: After filtering and stabilizing the DC power, the voltage and current are precisely adjusted and adapted according to the actual needs of the excitation system through specific circuits and control algorithms, and output to the excitation system in the appropriate form of electrical energy to ensure its stable operation.
