Is the inverter transformer coil more voltage high

First winding primary, after the primary winding, use capacitor paper or kraft paper to wrap three layers, as the primary insulation, and then winding the secondary, the secondary two 54 turns (the input of this transformer is 220 volts, the output is double 27V) according to this can be concluded that each circle is, that is, the primary is 440 circles. After the secondary winding, the second layer of capacitor paper or kraft paper is wound to insulate the iron core. Then insert the iron core, which can be crossed with three iron cores together.

After the core is plugged in, the power test, if the voltage meets the requirements, pour the insulating paint to dry. The layers of the coil can be insulated with capacitor paper or kraft paper between the layers. Tissue paper for beginners.

You can also do without. I have made a lot of transformers with this side. Works well.

The production of inverter transformer: you can choose a control transformer for machine tools according to your own needs. I use a 100w control transformer.

Disassemble the transformer core and remove the secondary coil. and record the number of laps per volt. The secondary coil is then rewound.

The enameled wire used is first wound around a 22V coil and tapped in the middle, which is the main coil. The re-used enameled wire is wound around two 4V coils for feedback coils, and the layers of the coils are insulated with thicker kraft paper. After the coil is wound, insert the core.

Connect the two 4V secondary stages to the main coil separately, and note that the pin connection of the head and tail is reversed. It can be energized to measure the voltage. If the voltage increases after the 4V coil and the main coil are connected, it means that the connection is correct, and vice versa.

The connector can be replaced. So that the transformer is done.

Selection of resistance. Two resistors connected in series with a 4V coil can be made with resistance wires. The size of the resistor can be selected according to the output power, generally a few ohms.

When the output power is large, the resistance is smaller, and the bias current resistance is 300 ohms of 1W. It works without this resistor. However, due to the inconsistent parameters of the tube, sometimes it does not vibrate, and it is better to take one.

Triode selection: three 3DD15 in parallel on each side. Six tubes are shared. After the circuit is connected, check that there are no errors, and you can power on and adjust.

Connect the battery and find a 100W incandescent lamp for the load. Turn on the switch and the bulb should glow normally. If it does not emit light normally, the resistance of the base can be reduced.

until it can glow normally. Then connect the color TV to see if it can start normally. Not starting properly is also a reduction in the resistance of the base.

After the adjustment, it can be used normally.

My inverter and charger are made in one chassis, and the outputs are connected in parallel to the AC power supply at home. And installed a relay, when the power fails, it can automatically switch to the inverter to supply power, and cut off the external circuit, and automatically connect the AC power to cut off the power supply of the inverter and turn into the charging state when the call comes. If there is no power outage call status indicator, you will not feel it when a power outage is called.

There is more primary, the secondary voltage is low, and the secondary voltage is high.

High pressure. Inverter.

It is an electronic device that converts a DC low voltage into a high voltage pulse. It is roughly a process of converting a low-voltage DC to a high-voltage AC.

First of all, DC voltage.

It is divided into two channels, one for the power supply to the pre-IC to generate a KHz level.

Control signals. All the way to the pre-amp.

Power tubes. The constant switching of the power tube is driven by a control signal.

High-frequency transformers.

The primary generation of low-voltage high-frequency alternating current (although the voltage of the alternating current at this time is low, but the frequency is quite high, the purpose is to make the transformer back-stage produce a high voltage, the frequency of the pre-stage is proportional to the voltage of the output of the post-stage, of course, it must also be in the frequency range that the power tube can bear) output high-frequency alternating current through the high-frequency transformer and then pass through.

Fast recovery diodes.

The full-bridge rectifier outputs a high-frequency DC of several hundred V to the power tube of the rear stage, and then the control signal of about 50Hz is generated by the power amplifier IC to control the work of the power tube of the rear stage and then output alternating current.

Of course, a complete inverter also needs some protection circuitry, such as:

Overload protection. Temperature protection, high and low messy input voltage protection and.

Filtering circuits. High-frequency circuits.

The filtering is also very important, because the high frequency is easy to produce some interference and parasitic coupling, so the sock bend gear needs to filter the circuit to filter out the influence of these factors to increase the stability of the circuit.

A high-voltage inverter is an electronic device that converts DC low voltage into a high-voltage pulse in a back-hole. It is roughly a process of converting a low-voltage DC to a high-voltage AC.

First of all, the DC voltage is divided into two ways, one is to supply power to the pre-stage IC to generate a KHz level control signal, all the way to the pre-stage power tube, and the control signal drives the continuous switching of the power tube to make the high-frequency transformer primary produce low-voltage Zheng Shiblind high-frequency alternating current (although the voltage of the alternating current at this time is low, but the frequency is quite high, the purpose is to make the transformer rear stage produce a high voltage, the frequency of the front stage and the output voltage of the rear stage are proportional to the air, of course, it must also be in the frequency range that the power tube can withstand) Through the high-frequency transformer, the output of high-frequency alternating current, and then through the rapid recovery diode, full-bridge rectification, output a high-frequency direct current of several hundred V to the post-stage power tube, and then by the post-amp IC to generate a control signal of about 50Hz to control the work of the post-stage power tube, and then output alternating current.

Of course, a complete inverter also needs some protection circuits, such as overload protection, temperature protection, high and low input voltage protection and filter circuits, and the filtering in high-frequency circuits is also quite important, because high-frequency is prone to some interference and parasitic coupling, so filter circuits are needed to filter out the influence of these factors to increase the stability of the circuit.
