Amplifier power supply using High Current Transformer
Power supply
Friends ever meet a problem power supply Circuit give current not enough. I has way this out give friends try apply. Follow this circuit High Current transformer parallel circuit make you have Current tall go up very. The transformer that have many the coil , we can bring to do high Current power supply circuit well. By if the all coil has Voltage be equal. It is can bring parallel can follow this circuit is coil lead that has Voltage 24V and have Current about 1A come to parallel prevent all 2 the group have current altogether each 2A groups …
9V Negative power supply units
Power supply
Today I find a negative power supply units circuit on 9Volt sizes to give my friends. But the most circuit is positive voltage supplies only. Therefore I think will get back to the direction of the electricity to negative form. When use Transistor 2SC1061 or TIP31 as a result give current about 1A and Transformer must have 1Amp size with. Now we change with TIP42 PNP transistor type and switch polarity of Zener diode, Electrolytic capacitors, and more other parts same one. Request have fun 9V Negative power supply units. but you want to builds easily maybe use IC-7909 dc …
