15 Watt switching power supply

A 15 Watt switching power supply schematic diagram features a pulse transformer T1 constructed on a ferrite core M2500NMS-2 or M2000NM9, with a Sh5h5 size (cross-section of the magnetic coils at the location of 5G—5 mm with a gap in the center). The winding wire is of brand PEL-2. The first winding consists of 2 turns of wire containing 600 strands of 0.1 mm in diameter, while the secondary winding has 3-4 turns of 0.25 mm diameter wire and 5-6 turns of the same wire as the primary winding. This schematic diagram is derived from the circuit labeled "Simple Switching Power Supply 15 Watt." This 15 Watt power supply can efficiently power any load up to 15-20 watts and has a smaller form factor compared to similar designs utilizing a step-down transformer operating at a frequency of 50 Hz. The device is capable of handling input voltages up to 40,000 volts from a 220V AC source. The AC to AC converter circuit is powered from the mains through a primary transformer (220-24), providing isolation from the network while reducing the input voltage. Additionally, the core of the circuit acts as a DC to DC converter, converting 12V to ±38 VDC, and incorporates a pulse generator based on the TL494 chip. This circuit is also designed to supply power to a monoblock car amplifier, specifically the TDA7294. The generator frequency can be adjusted as needed. Furthermore, the schematic includes a motorcycle battery charger designed specifically for charging motorcycle batteries, featuring a low charge current to prevent premature failure of the battery plates. The circuit generates a controlled current output. It is essential to note that the power supply is a critical component of any amplifier, as a high output requires more than just a 12-volt battery. Consequently, a voltage converter is necessary to create a bipolar supply of -60V.

The 15 Watt switching power supply circuit operates by utilizing a pulse-width modulation (PWM) technique, which is essential for regulating the output voltage and current efficiently. The TL494 integrated circuit serves as the heart of the PWM controller, managing the switching frequency and duty cycle to optimize the power conversion process. This design allows for a compact and lightweight power supply solution, making it suitable for applications where space is limited.

The pulse transformer T1 plays a crucial role in transferring energy from the primary side to the secondary side while providing electrical isolation. The choice of ferrite core material, such as M2500NMS-2 or M2000NM9, ensures high efficiency and minimal losses during operation. The winding configuration, with specific turns of different wire gauges, is designed to achieve the desired inductance and impedance matching for optimal performance.

In terms of output capabilities, the power supply can deliver stable voltage levels suitable for various electronic devices, including audio amplifiers and other consumer electronics. The ability to handle input voltages of up to 40,000 volts highlights the robustness of the design, making it versatile for different applications. The built-in motorcycle battery charger functionality ensures that the circuit can also serve as a maintenance tool, prolonging the life of motorcycle batteries through controlled charging.

Overall, this 15 Watt switching power supply schematic represents a well-engineered solution for powering low to moderate power electronic devices while maintaining efficiency, compactness, and reliability.15 Watt switching power supply schematic diagram.
