35 Ampere Power Supply

Description: A 12 Volt 35 Amp power supply can be constructed using the LM7812 voltage regulator to provide a stable 12 Volt DC output. The power supply employs TIP2955 transistors as the main power regulators, with a configuration that utilizes six TIP2955 transistors. The choice of MJ2955 over TIP2955 is made due to the easier installation of heatsinks with the TIP2955 packaging. The series configuration allows the power supply to handle loads up to 35 Amps, depending on the transformer used. This design is straightforward, as it relies on the IC7812 voltage regulator, allowing the power regulation to be managed independently. For further details, a schematic representation of the 12 Volt 35 Amp power supply is provided in the accompanying figure. To achieve the maximum current of 35 Amps, it is essential to maintain the circuit with the six TIP2955 power regulators as illustrated in the above image of the series 35 Ampere power supply.

The 12 Volt 35 Amp power supply circuit utilizes the LM7812 voltage regulator, which is designed to provide a constant output voltage of 12 Volts. The LM7812 is a linear voltage regulator that requires a minimum input voltage higher than the output voltage, typically around 15 Volts, to function effectively. The circuit is complemented by a transformer that steps down the AC mains voltage to a suitable level for the LM7812 input.

In the power regulation stage, six TIP2955 transistors are arranged in a parallel configuration to share the load current. Each TIP2955 can handle significant current, but by using multiple transistors, it is possible to distribute the heat generated during operation, thereby enhancing reliability and performance. The MJ2955 transistors are preferred for their thermal characteristics and ease of mounting heatsinks, which are critical for dissipating heat in high-current applications.

The circuit design also incorporates necessary protection features, such as fuses and heat sinks, to prevent damage from overcurrent conditions. The output is typically filtered with capacitors to smooth the DC voltage, ensuring a stable power supply for connected loads. The overall layout should consider proper grounding and trace width to handle the high current, minimizing voltage drop and enhancing efficiency.

This power supply is suitable for various applications requiring a reliable 12 Volt DC source with high current capability, such as powering motors, LED arrays, or other electronic devices that demand substantial power. The simplicity and effectiveness of this design make it a popular choice among electronics enthusiasts and engineers alike.To make 12Volt 35 Amp Power Supply such as those titles can using LM7812 voltage regulator as the regulator 12 Volt DC and as a power supply can use transistor TIP2955. Series Power Supply 12Volt 35 Amp uses 6 units TIP2955 type power regulator transistors. I use a type MJ2955 TIP2955 not because packaging TIP2955 easier to install heatsink. The series 12Volt 35 Amp Power Supply can be loaded up to 35A depending on the travo which we attach. The series 12Volt 35 Amp Power Supply is very simple, because the voltage regulators make use of IC7812 which will leave a power regulator alone. For more details, series 12Volt 35 Amp Power Supply can be seen in thethe following figure. If want the maximum currents up to 35A not only reduced the live circuit TIP2955nya power regulator, no need to 6 levels as seen in the image series 35 Ampere Power Supply 12Volt above.
