Instructions:

Products are modified wave inverter correction sine wave inverter, can be modified wave

inverter 3000W, etc ..., modified pure sine wave inverter.

First, after the correction of the inverter inverter power tube removed, and then look at the

correction of a few transformers transformer, 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 tandem type, plus 8 laps per transformer

secondary. Then in the correction transformer which transformer 1 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

transformer with the parameters of magnetic ring) After the addition of transformer

parameters, we must correct the inverter inverter high voltage capacitors in exchange

for 220UF / 450V, ''Remember: correction inverter inverter high-voltage capacitor has a

positive feedback Resistance, the resistance of a few hundred K, but also for large point

resistance, not the voltage will not rise. After testing the voltage of high-voltage capacitor  (positive

/ negative) voltage DC380V, the test voltage is normal, the use of cable to the sine  wave after

the board, after the board output voltage: AC220V / 50HZ, the output waveform: pure sine wave.
