Description: This is the schematic diagram of a 15W inverter circuit. The circuit is based on a PNP power transistor such as the TIP32 and other similar transistors. This inverter produces a square wave output, which may cause some noticeable hum in audio units powered by this inverter circuit. To reduce some of the hum, it is recommended to increase the value of the output capacitor to 0.47µF. The transformer used will have a center-tapped secondary rated at 24 volts and 2 amperes.
The 15W inverter circuit utilizes a PNP power transistor, specifically the TIP32, which is designed to handle the necessary current and voltage levels for efficient operation. The circuit configuration is intended to convert a DC input into a square wave AC output, suitable for powering various devices, albeit with some limitations in terms of output waveform quality.
The square wave output is characterized by its abrupt transitions between high and low states, which can introduce audible hum when connected to audio equipment. This is due to the harmonic content of the square wave, which includes a fundamental frequency and its odd harmonics. To mitigate this issue, the output capacitor's value can be increased to 0.47µF, which helps to filter some of the high-frequency noise and smooth the output waveform, thus reducing the hum.
The transformer plays a critical role in this inverter circuit. It is specified to have a center-tapped secondary winding rated at 24 volts and 2 amperes. This configuration allows for the generation of a dual voltage output, providing both positive and negative halves of the square wave. The center tap serves as a ground reference, which is essential for the proper functioning of the circuit.
In summary, this 15W inverter circuit is a practical solution for converting DC power to AC, utilizing a PNP transistor and a transformer. While the square wave output may introduce some noise in sensitive audio applications, adjustments to the output capacitor can help mitigate these effects, making the circuit more suitable for a wider range of applications.This is the schematic diagram of 15W inverter circuit.
