Challenges and Solutions

Issue with MOSFET Driver (IR2103):

The IR2103 MOSFET driver can encounter issues when connected to a 12V supply. The high-side output delivers 12V instead of the expected 6V. This occurs due to a 5-second delay in the microcontroller’s HEX file, causing the high side to turn on while the low side remains off. This can directly trigger the MOSFETs with voltage, potentially damaging the circuit.

Solution – Adding a Delay Timer Circuit:

To resolve this, a 5-second delay timer circuit is added. The timer output is connected to the VCC pins (1 and 8) of the IR2103, ensuring proper synchronization between the microcontroller and the MOSFET driver. This prevents premature activation of the MOSFETs and protects the circuit.

The SG3525 is a PWM regulator that can be used to control the output voltage and current of power. By adding a few extra components, it can be used to convert a 12V DC input to a 310V DC output.

Here is a step-by-step guide on how to use the SG3525 to build a 12V to 310V DC power supply:

Selecting the transformer: To convert the low-voltage input to a high-voltage output, you will need to choose a step-up transformer. One option is to select a transformer with a turns ratio of around 1:25. This implies that the secondary winding will have a significantly greater number of turns compared to the primary winding. For a 12V input, a suitable transformer would have a secondary voltage rating of approximately 300V.

Make the necessary connections: Ensure that the SG3525 is properly connected to the input voltage, ground, and feedback pin. The feedback pin is used to control the output voltage. For this application, we will use voltage mode control with the SG3525, which can be designed to operate in either voltage mode or current-mode control.

Connect the transformer: Connect the primary winding of the transformer to the output of the SG3525. The secondary winding should be connected to the diode and capacitor network.

Include the diode and capacitor network: This network is used to rectify and filter the output voltage. A full-wave rectifier can be used with two diodes connected in a bridge configuration. To smooth the filtered output voltage, you can connect a capacitor in parallel with the output.

Include the output load: Connect the load to the output of the power supply. Ensure that the load remains within the maximum current rating of the SG3525 and the transformer.

Make adjustments to the SG3525 in order to achieve the desired output voltage. This task can be accomplished by making adjustments to the feedback voltage. This can be done by using a potentiometer or trimmer resistor that is connected to the output and feedback pins of the SG3525.

There are a few important considerations to keep in mind when constructing a power supply using the SG3525:

Component selection: Choose reliable components capable of handling the voltage and current ratings of the power supply. Using subpar components can result in the power supply becoming unstable and ultimately failing.

Caution: High voltage DC poses a significant risk and can be potentially life-threatening. Ensure that the power supply is properly insulated and that necessary safety precautions are taken when dealing with the circuit.

Improving productivity in the power supply can be achieved by selecting a transformer with a high turn ratio and reducing losses in the diode and capacitor network.

To summarise, the SG3525 can be used to create a high-voltage DC power supply by regulating the output voltage and current. By carefully selecting components and prioritizing safety and efficiency, the SG3525 can become a valuable tool for powering a range of electronic devices.

Attach the 270kΩ resistor to pins 2 and 3 of the IR2153 IC

Attach the 470Ω resistor to the MOSFET gate driver.

Connect one of the MOSFET’s drain pin to one side of the transformer and the second MOSFET’s drain to the other side of the transformer.

Ensure that the sources of the MOSFETs are properly connected to the DC source.

Lastly, attach the heat sink to the MOSFETs for effective heat dissipation.

Test the inverter with a power load of up to 200 watts, just like an electrical engineer would do.

In conclusion:

A push-pull inverter utilizing MOSFETs, such as the IR2153, is an efficient and dependable option for converting DC voltage into high AC voltage. Ensure precise soldering of the MOSFETs, utilizing the appropriate component rating and adhering to their polarity. Exercise caution when handling the circuit, as it involves a high-voltage project.

A sine wave inverter converts DC (Direct Current) power into AC (Alternating Current) power. It is commonly used in applications such as solar power systems, UPS (Uninterruptible Power Supply) systems, and portable power systems for camping or outdoor use.

The DSPIC30F2010 microcontroller is widely recognized for its exceptional performance and affordability, making it a popular choice for implementing sine wave inverters. In this article, we will explore the design and implementation of a sine wave inverter using the DSPIC30F2010 microcontroller.

Design Considerations:

Before embarking on the design of the circuit and code for the sine wave inverter, it is important to take into account several design considerations. Here are some examples:

The size of the components used in the circuit will be determined by the resulting power of the inverter. The power output can vary from a few watts to several kilowatts, depending on the specific application.

The voltage output of the inverter will depend on the specific application. As an electrical engineer, you may encounter different voltage outputs in a solar power system, such as 120V AC or 240V AC.

The outcome recurrence of the inverter will depend on the application. As an electrical engineer, it’s worth noting that the standard frequency in the US is 60Hz, whereas in Europe it’s 50Hz.

Efficiency is a crucial factor to consider when evaluating the inverter’s impact on the overall performance and cost of the system. An inverter with improved efficiency will result in reduced power consumption and lower output intensity.

The waveform of the resulting signal is an important consideration. A pure sine wave output is the preferred waveform as it produces minimal harmonic distortion and poses less risk of damaging delicate devices.
