Description

This is electronic circuit of Electronic Circuit: Amplifier Power Supply 24V 2A Based on TIP122 for you. According Eleccircuits blog mentioned that when the load-use many currents. The output voltage still voltage of 24V, and low ripple. So low noise on the speaker of your amplifier. Of cause, we can use this circuit for any circuit and can change voltage output as you need. And this circuit has a few parts and easy to buy in most of the local markets.

The AC-voltage to the power cord, transformer T1 changes 230VAC(PRI) to about 24VAC(Sec). Then, the rectifier bridge, D1 through D4, rectifies the AC into pulsating DC.

Next, A big electrolytic capacitor-C1 filter the pulsating DC to smooth DC voltage about of 36V. But this is not complete. Because of It is not DC regulated voltage of 24V at 2A.

After that, the DC voltage flow through the R1 to Zener Diodes (ZD1, ZD2) to keeps the voltage constant at 25V. This voltage across the base of Darlington transistor Q1 to bias it working full current more than of 2A.

The capacitors C2, C3, C4 acts as a storage capacitor to reduce the noise of output. This makes constant voltage across the output of 24V. The LED1 show power on of circuit, which the R3 is its limiting current resistor.

Long-pressing the button on the right side (holding it for >2 s) makes the module enter calibration mode. After releasing the button, the related LED will blink to indicate which voltage is now calibrating, and the numeric display will blink with the present value.

Short-press the button to change the present value. For example, if your power supply is 6 V but the result of voltage meter is 5.8 V, you need to set the value to 6 V. Short-press the button on the right side to increase the voltage by one unit. Short-press the button on the left side to reduce the voltage by one unit.

Long-press button on the right side to store the redressed value. The preset pot sets the actual output voltage. Calibrate the output voltage reading on the digital voltmeter in the same way above. For example, if your actual output is 3 V but the result on the voltmeter is 4 V, you need to set the value to 3 V. The redressed value will be stored in the non-volatile memory of the module.

Description

The electronic circuit design like in Figure 1 above show you power inverter circuit using IRFP540. Other component need also that can supply with low voltage DC +12V and ground source to charge this IC and all system component from power supply built. With this electronic design circuit you can produce White / LF noise generator that useful now.

According Eleccircuits blog mentioned that as 200 watts inverter circuit. We use Q1, Q2 is the mosfet acts as a power output. That can withstand currents up to 18A. According to properties listed in the table of Figure 2. If the circuit is fully functional with maximum power of 12V x 18A = 216 watts. But in practice, the circuit should work up, it may be damaged. Therefore, it is designed to operate up to 200 watts.

Since we want the current more than 40A. But the power mosfet single, able to withstand current is 18A, therefore have to be 3 pcs. And When designing a circuit in a push-pull model thus requires a power mosfet 3 pairs.

We have the output current up to 54A which can withstand more demanding than 14A. It is good for the operation of the circuit. Because each power mosfet will not be overburdened. And the heat of the mosfet least, the lifetime of the life circuit.

In Figure 3 is the inverter circuit with a power output Increased at least 2 pairs and use the 12volts 40A transformer, so that the power output 500 watts.

According Electroschematics blog mentioned that solar window chargers have several advantages when compared with other charger types. You can stick this DIY solar window charger to the inside of a glass window with the solar panel facing out and then connect its output to any USB-chargeable portable device through a suitable cable. The charger itself contains a lithium-ion battery to give an uninterrupted and clean dc supply output and has a cool multipurpose light source built in!

The charger’s electronics consist of a small 5-V/500-mA solar panel (SP1) linked to a Li-ion battery charger circuit built around the dedicated Li+ charge controller chip MAX1555 (IC1). The rest of the circuit portion corresponds to the usual minimum configuration of a pre-wired dc-dc boost converter module (M1), which can render USB-standard dc supply output to the external load through its standard USB connector. The circuit’s built-in power supply has been kept very simple. The single-cell Li-ion battery (BAT) provides a nominal voltage on 3.7 V. The power supply also drives a “luxury” white LED light source (LED2–LED4).

Description

The electronic circuit design like in Figure 1 above show you portable power inverter circuit using the major component called with CD4047 IC. In here we can use 12V source to charge this IC. This is IC for the monostable/astable multivibrator.

According Electroschematics blog mentioned that the circuit is built around the monostable/astable multivibrator CD4047 (IC1). The resistor (R2) and capacitor (C3), connected to pins 2 and 3, will decide the frequency of the astable output pulses (here, it is at about 50 Hz). IC1 gives two similar frequency outputs at pins 10 and 11 (phase of the Q and Q signals varies about 180 degrees). The square wave output signals are processed by the two-channel transistor banks (T1-T3-T5 and T2-T4-T6) to drive the power transformer (TR1). In my prototype, TR1 is a 60-VA toroidal transformer with a nominal 12-V rms secondary and 5-A current. I have powered up the inverter with an SMF battery of 12 V close to 7 Ah and successfully powered one 230-V/40-W lightbulb. The efficiency looks promising with neither the MOSFETs nor the transformer getting hotter than warm.

Because the inverter has fatal mains voltages present, it is highly recommended that it be put into a metal enclosure (with adequate vent holes). The largest component is the toroidal transformer, which should be securely mounted to the chassis. A proper (TO-220) heatsink should be used with the FETs (T5-T6). Note that both the upper and lower FETs can be bolted into a single (TO220x2) heatsink plate, provided that they are insulated from each other and from the heatsink plate.
