An interesting circuit transformer core DC12 volts to DC24 volts dc upgrades have been made obsolete n555 number 3 connected to the output end 2sj302 MOSFETs with opto-up Kubla circuit charging source is being used to supply power can give 1.5 to 2 amps In response to the output diode by399 can use 4N25 opto…
Low-power to run a variety of devices lm2585-adj made with simple solar power system 6V dc converter 15v can be useful Using the LM2585 (NationalSemiconducter), I tried to assemble this time. I’ve lost my output to 15V/400mA. Input at this time, in a reasonable 73 percent conversion efficiency in 6.8V/1.2A. Referring to the documents of…
DC DC Converter Circuit is based on sg3525 smps control IC, it can provide 900w power. The power transformer used is etd59 output 4n25, isolated with opto coupler, it gives a symmetrical + – 70 volts total 140 volts output with 12 volts. There is a pcb file prepared with ares that can be used…
MC34063 (njm2360) and 12V input 320V output dc dc converter circuit guess a small 37 inch television run, but such an application to experiment with I output of the circuit to be isolated because of how the results do not know what more to be mixed and less material is used for the short time…
Lamp Flasher Circuit NE555 integrated control of 220 volt mains supply for over-current through the resistor capacitor and so on. taken with passive elements so no need to use a transformer to supply RV1 and RV2 brightness of the lamp flashing speed can adjust the lamp power used to control the triac (bt136 bt139 available)…
Modification of the LM723 2N3055 stabilized power supply. I have always been concerned that the voltage drop is large when a load is applied and this is clearly visible even with a 30V voltmeter. (After adjusting the voltage with no load, 100 to 200mV drops when 3 to 4A load is applied) In particular, when…
Lithium-ion rechargeable battery, charging in a constant voltage constant current system. Charger No-load voltage is a deep discharge battery check if below 2.9V per cell 0.1ltmA after charging at a certain time than 3.0V per cell stop Check voltage imbalance in every cell battery voltage, if abnormal voltage stop One is a single cell voltage…
The input voltage is 12v, the output is adjustable between 12-24 volts. It has 5 ampere power. The coil used is 50μH 5 amps. Setting the LM2588-ADJ output voltage is determined by the resistance values of R1 and R2. Output can be adjusted by using a series or direct trimpot to the R1 resistor. LM2588-ADJ…
A simple useful Power control circuit can be used for 12v lamp dimming dimmer or motor 12 volt motor speed control. In the circuit diagram, the driver appears as integrated 7555, don’t be fooled, you can use the 555 timer IC. This integrated is produced by many companies. There may be name differences. It seems…
12V 230V Inverter Circuit Built on cd4047 cmos monostable/astable multivibrator integrated, the 12v battery voltage increases to 230v ac, the output frequency can be adjusted as 50hz or 60hz. Input voltage 12V DC, Output 230VAC / 50 / 60Hz Possibility to change Square wave Output Frequency from 50Hz to 60Hz. Efficiency between 80-85% This simple…
