Inverter diagram Op-Amps Circuits Simple

An inverter is a device that converts DC power (battery) into AC power (usually sine or square waveform, 220V | 50HZ). Our conventional emergency power supplies typically convert battery DC to 220V AC. Simply put, an inverter is a device that converts direct current into alternating current. Whether you are in a remote village, need it in the wilderness, or have an emergency power outage, an inverter is a very good choice. More commonly, UPS power supplies are used in computer rooms. In the event of a sudden power outage, the UPS reverses the DC power in the battery to AC for use by the computer, thus preventing data loss due to a sudden power-off. This article will introduce two relatively simple inverter circuit diagrams. A simple inverter circuit diagram is attached. For those of you who are interested, being able to research and make your own inverter is truly a very satisfying thing. The following is a common inverter circuit diagram.

Above is an inverter circuit diagram that is relatively easy to make. It can invert 12V DC power voltage to 220V power voltage. The circuit is controlled by the harmonizer consisting of BG2 and BG3, and controlled by BG1 and BG4. BG6 controller works with BG7. The oscillator circuit is powered by the adjustable power supply of BG5 and DW groups, which can make the output frequency more stable. During production, the transformer can be selected from a conventional power transformer with dual 12V output. You can choose the appropriate 12V battery capacity according to your needs.

The following is the electrical diagram of a high-efficiency sine wave inverter.

The circuit is powered by a 12V battery. First, use a voltage doubler module to double the voltage to power the op-amp. You can choose ICL7660 or MAX1044. Op-amp 1 generates a 50Hz sine wave as a reference signal. Op-amp 2 acts as an inverter. Op-amp 3 and op-amp 4 act as delay comparators. Actually, op-amp 3 and switching tube 1 form a proportional switching power supply. The same thing happens with op-amp 4 and switch tube 2. Its switching frequency is unstable. When the output signal of op-amp 1 is positive phase, op-amp 3 and the switching tube are active. At this time, the output of op-amp 2 is negative phase. At this time, the input anode potential of op-amp 4 (constant) is always higher than the input cathode potential, so the output of op-amp 4 is always equal to 1 and the switch tube is turned off. When the output of op-amp 1 is negative phase, the opposite is true. This allows the two switching tubes to operate alternately.

Explanation of operating principle:

When the reference signal is higher than the detection signal, that is, the signal at the negative input terminal of op-amp 3 or 4 is higher than the signal at the positive input terminal by a small value, the comparator outputs 0, the switch in the enabled state, and the detection signal increases rapidly. When the detected signal has a value slightly higher than the reference signal, the comparator will output 1, and the switch will turn off. What should be noted here is that the comparator has positive feedback when the circuit reverses, which is a characteristic of a hysteresis comparator. For example, under the premise that the reference signal is lower than the detection signal, as their difference continues to approach, at the moment they become equal, the reference signal is immediately higher than the detection signal by a certain value. This "certain value" affects the switching frequency. The larger it is, the lower the port frequency. Here it is chosen as 0.1 - 0.2V. The function of C3 and C4 is to allow the free current of the higher frequency switch to pass and create a greater impedance for the lower frequency 50Hz signal. C5 is derived from the formula: 50=1/(2πfC). L is usually 70H; it is best to check it when making. In this way, C is about 0.15μF. The ratio of R4 and R3 must be exactly 0.5. If it is larger, then the waveform distortion will be obvious, and if it is smaller, then it will not start to vibrate. However, it is better to be larger than smaller. The maximum current of the switch tube is: I=25A.

There are currently two types of inverters: 

square wave output and sine wave output. The inverter has a high-efficiency square wave output. For electrical appliances designed with sine wave power, most electrical appliances can be used, except for some electrical appliances with sine wave output, which do not have this drawback. Low efficiency is a choice that depends on your own needs.
