The product is modified wave inverter charge sine wave inverter, can make modified wave inverter 3000W, etc ...,
as modified pure sine wave inverter. First, remove the power tube after correction inverter, and then look at the
correction inverter have how many transformers, look at the transformer secondary circuit is connected in parallel or in series, and then add the transformer parameters, modified wave transformer secondary is parallel, In each transformer secondary plus 16 laps.
The secondary of the modified transformer is a series type, plus 8 laps per transformer secondary. Then in the correction transformer which transformer one empty foot plus a small voltage parameter, the small voltage parameters using 0.6 copper wire, in the transformer inside around: 5 laps, the small voltage is linked AC: 16V position. (Note: Do not open the magnetic ring when the added transformer with the parameters) After the addition of transformer parameters, we must correct the modified wave inverter high voltage capacitors in exchange for 220UF / 450V, Remember: modified wave inverter high-voltage capacitor has a positive feedback Resistance, the resistance is a few hundred K, but also need to change a large resistance, or the voltage will not rise. After testing the voltage of high-voltage capacitor (positive/negative) voltage is DC380V, the test voltage is normal, the use of the cable to the sine wave after the board, after the board output voltage: AC220V / 50HZ, the output waveform is pure sine wave.
