A charging method for negative and positive pulse

Abstract

The invention relates to a positive and negative impulse charge method, which adopts a 220V AC rectified 100Hz pulsation DC to directly carry out the transformation of the positive impulse. The positive and the negative impulses are transferred in the same impulse transformer B. A charging area and a charging stop area related with the pulsation DC are provided. When the pulsation DC voltage crosses a zero point and the voltage of a check point A rises to 120V, the positive impulse transfers the circuit and starts to work; while, when the voltage drops back to 90V, the positive impulse converter stops working. When the charge stops for a period, the negative impulse transfers the circuit and starts to work, the energy electric of storage battery then charges for the stored capacitor C3 and the negative impulse lasts 0.2 to 1mS and stops. The positive impulse again transfers the circuit and starts to work until the next pulsation DC voltage rises to 120V. The invention has the advantages that according to the change regulation of the AC, the invention arranges the positive and negative impulse to work to make the whole power supply stable and the power factor high; the positive and negative impulse are transferred in the same transformer, and the discharge of the negative impulse is stored in the capacitor C3 for the next positive impulse charge use.

Description

technical field [0001] The invention relates to the charging field, and mainly relates to a positive and negative pulse charging method. Background technique [0002] The original positive and negative pulse position arrangement is artificially set. Generally, after 220V rectification, it is filtered by a large electrolytic capacitor or converted into a direct current through power conversion, and then the positive pulse charging conversion is performed. After charging for a period of time, the positive pulse charging conversion stops, and the negative pulse When the conversion starts, the negative pulse discharge will stop after a certain period of time, and then the positive pulse conversion will start again. Such an artificial setting of positive and negative pulse intervals is very random, and the negative pulse area will not be set near n180°-17°~n180°+23° where the AC power supply capacity is weak, and the frequency is often lower (less than 10Hz). When charging with...

Problems solved by technology

When charging with a large power, the power of the grid will fluctuate with the alternation of positive and negative pulses, and the voltage of the grid will also fluctuate accordingly, which will cause the bulb to flicker at low frequency and the motor to vibrate, causing damage to electrical appliances and affect lighting comfort

In addition, some positive and negative pulse converters divide power factor conversion, positive pulse charging conversion and negative pulse conversion into three transformers or inductors, and are equipped with a set of single-chip microcomputer control components. The circuit is complex and costly, and it also brings pollution to the power grid.
