What is three-phase alternating current? Presumably most of the friends engaged in the electrical industry are not strange, but for a beginner it may be half understood. In fact, three-phase alternating current is a form of power transmission, referred to as: three-phase electricity. General household electricity is single-phase AC, but the large-scale production and distribution …
The experimental circuit is as follows: Components and parameters: Resistors are RJ14 type resistors with an accuracy of 0.1%, R1=100kΩ, R2=R3=10kΩ, R4=12kΩ, R5=3kΩ. There are two sets of capacitors for comparison: one is a CB4 type capacitor with a high Q value, with a capacity of C1=C2=14.66nF and Q>20000. The other group is the common …
An active filter is a type of analog circuit that implements an electronic filter using the active component, usually an amplifier. The amplifier included in the filter design can be used to improve the cost, performance and predictability of the filter. First, how to design active filter The design method of active filter can be …

SVG is a typical power electronic equipment, which is composed of three basic functional modules: detection module, control operation module and compensation output module. Its working principle is to detect the current information of the external CT system, and then analyze the current information, such as PF, S, Q, etc., through the control chip; Then the controller gives the compensated drive signal, and finally the inverter circuit composed of the power electronic inverter circuit sends out the compensated current.
Static reactive power generator is the self-commutating bridge circuit through the reactor or directly connected to the power grid, adjust the phase and amplitude of the AC side of the bridge circuit output voltage, or directly control its AC side current, so that the circuit absorbs or sends out the reactive power to meet the …
Active Power Filter (APF) is a new type of power electronic device used to dynamically suppress harmonics and compensate for reactive powerlessness. It can compensate for harmonics that change in size and frequency and reactive power.Active filters are called active. As the name implies, the device needs to provide power supply (to compensate for the …
