![]() This voltage can be used to heat your small electronic devices such as lamp, soldering iron, battery charger etc. When you power the circuit using switch S1, transformer X1 produces 230V AC at its primary terminal. The centre-tapped terminal of the secondary of the transformer is connected to the battery (12V, 7Ah), while the other two terminals of the secondary are connected to the collectors of power transistors T7 and T8, respectively. The outputs from the drivers are fed to transistors T5 and T8 (2N3055) connected for push-pull operation.Ī 230V AC primary to 12V-0-12V, 4.5A secondary transformer (X1) is used. The complementary outputs from collectors of transistors T1 and T2 are given to PNP darlington driver stages formed by transistor pairs T3-T4 and T6-T7 (utilising transistors BD140 and 2N6107). For obtaining correct frequency, the values of resistors R3 and R4 may have to be changed after testing. The function is COMPLEMENTARY SILICON TRANSISTORS.Transistors T1 and T2 (BC548) form a 50Hz multivibrator. The function is GENERAL PURPOSE TRANSISTOR(NPN SILICON). The function is MEDIUM POWER SILICON NPN PLANAR TRANSISTOR. ![]() They help customers to save time and money by providing a one-stop-shop for all their component needs. Electronic components distributors play a crucial role in the electronics industry by providing easy access to the components. They offer a wide range of electronic components, including semiconductors, resistors, capacitors, connectors, and many others. An electronic components distributor is a company that sources, stocks, and sells electronic components to manufacturers, engineers, and hobbyists.
