Headphone socket to see what is the current and voltage method, the specific details we will give you a detailed introduction below.
The full wave rectifying circuit of headphone socket can be regarded as composed of two half wave rectifying circuit groups. The transformer secondary coil center needs to lead out a tap to divide the secondary coil into two symmetrical windings, and then lead out two voltages E2A and e2b with the same size but opposite polarity to form E2A.
The hard start of the motor has a severe impact on the power grid, and it also requires too much capacity of the power grid. The large current generated during the start and the sensation do great harm to the baffles and valves, and are extremely detrimental to the service life of the equipment and pipelines. After using the frequency conversion energy-saving device, the soft starting function of the frequency converter will make the starting current start from zero, and the maximum value will not exceed the rated current, reduce the impact on the power grid and the request for power supply capacity, and extend the service life of the equipment and valves.
The specific method of headphone socket is divided into flux open-loop and flux closed-loop. Flux open-loop method uses two non-zero vectors and one zero vector to form an equivalent voltage vector, if the sampling time is small enough.
