DC-TO-DC CONVERTER WITH FREEWHEELING CIRCUITS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17966084 titled 'DC-TO-DC CONVERTER WITH FREEWHEELING CIRCUITS
Simplified Explanation
The present disclosure is about a DC-to-DC converter that has a wide input and wide output range and a linear voltage gain. It includes a first port connected to a first full bridge and a transformer connected to the first full bridge and a second full bridge. The converter also has a second port connected to the second full bridge, a first inductor connected between the second full bridge and the second port, and a first freewheeling circuit consisting of a diode and a switch connected in series.
- The DC-to-DC converter has a wide input and wide output range, allowing it to handle a wide range of input and output voltages.
- The converter has a linear voltage gain, meaning that the output voltage is directly proportional to the input voltage.
- The first freewheeling circuit, consisting of a diode and a switch, provides a path for the current to flow when the switch is turned off, preventing voltage spikes and protecting the components.
- The transformer allows for isolation between the input and output, ensuring safety and preventing noise interference.
- The first inductor helps to smooth out the output voltage and current, reducing ripple and improving efficiency.
Potential Applications
- Power supplies for electronic devices
- Renewable energy systems
- Electric vehicle charging systems
- Industrial automation and control systems
Problems Solved
- Limited input and output voltage range of traditional DC-to-DC converters
- Non-linear voltage gain in conventional converters
- Voltage spikes and potential damage to components
- Lack of isolation between input and output
Benefits
- Wide input and output voltage range allows for flexibility in different applications
- Linear voltage gain provides accurate and predictable output voltage
- Freewheeling circuit protects components and prevents voltage spikes
- Transformer provides isolation for safety and noise reduction
- Inductor helps to improve efficiency and reduce ripple in the output voltage and current.
Original Abstract Submitted
The present disclosure relates to a DC-to-DC converter. The DC-to-DC converter includes a first port coupled to a first full bridge and a transformer coupled to the first full bridge and to a second full bridge. The DC-to-DC converter further includes a second port coupled to the second full bridge; a first inductor coupled between the second full bridge and the second port; and a first freewheeling circuit including a first diode being coupled in series with a switch. The first freewheeling circuit is further coupled in parallel with the first inductor between the second full bridge and the second port. Thereby, the DC-to-DC converter has a wide input and wide output (WIWO) range and a voltage gain that is linear.
