Description: This is a heavy diet, which can deliver 10A stabilized. The circuit is built around a normal 78xx controller, but for extra power equipped with T1. For the 78xx can be taken any type. Keep in mind that the input voltage of 3V regulator must be higher as the output connected. See 78xx power for the available controllers. T1 must be a large heat sink mounted when large capacities are diminished. A negative variant of this diet is here to find. More: R1, R2 = 0.18 ? 5W R3 = 2.2 ? 2W C1 = 22000?F C2, C3 = 1?F B1 = 35A T1 = MJ15004 IC1 = 78xx
The circuit described is a high-current power supply capable of delivering a stabilized output of 10A, utilizing a linear voltage regulator from the 78xx series. The 78xx series includes various voltage regulators that can provide different output voltages, thus allowing for flexibility in design based on the required output. The input voltage to the regulator must exceed the desired output voltage by a sufficient margin to ensure proper regulation.
The power handling capability of the circuit is enhanced by the inclusion of a power transistor (T1), specifically the MJ15004, which is a high-power NPN transistor. This component is crucial for managing the increased current demands and should be mounted on a substantial heat sink to dissipate heat effectively, especially under high load conditions. The heat sink is necessary to prevent thermal overload and ensure reliable operation of the circuit.
Resistors R1 and R2 are specified as 0.18 ohms with a power rating of 5W, which suggests they are likely used for current sensing or as part of a feedback loop to stabilize the output. R3, with a value of 2.2 ohms and a power rating of 2W, could be used for additional current limiting or as part of a voltage divider configuration.
Capacitors C1, C2, and C3 are integral to the circuit's performance. C1, with a capacitance of 22000 µF, acts as a bulk filter capacitor, smoothing the output voltage and providing energy storage to handle transient loads. C2 and C3, both rated at 1 µF, are likely used for high-frequency decoupling, ensuring stable operation of the regulator by filtering out noise and providing a clean power supply.
The circuit also includes a fuse (B1) rated at 35A, which serves as a protective measure against overcurrent conditions, safeguarding both the circuit and connected loads.
Overall, this heavy-duty power supply circuit is designed for applications requiring significant current, with careful consideration given to thermal management, filtering, and protection to ensure stable and reliable operation.This is a heavy diet, which can deliver 10A stabilized.
