DIY 15-450V Boost Module for Power Experiments
Are you curious about the boosting effect of a 15-450V boost energy storage module? Check out this article.
The isolation transformer has an input range of 15V-48V and an output range of 130V-460V. It is used to power subsequent switch-mode power supply experiments, preventing fuse blows and trips. You can see the waveforms of all key points within just 1-2 cycles of the mains frequency under experimental conditions. Even in the event of a short circuit, it’s unlikely to blow a fuse; at most, it might cause a breakdown, which can be adjusted based on actual conditions and the capacitance size.
Here's the boosting effect diagram:
Using a 15V 3A adapter for power supply:
Input: 15-48V, Maximum Output: 460V. The circuit has both constant voltage and constant current adjustment resistors (RX24 gold discharge resistors). If you can't find plastic screws for fixing, you can temporarily use cable ties.
Discharge switch, the ON/OFF position is not grounded properly.
Power switch, the ON/OFF position is not grounded properly.
Using a multimeter for reference, the isolation transformer uses Rubycon capacitors.
Five capacitor boards are stacked together. The number of energy storage boards can be increased or decreased based on actual needs.
Rubycon capacitors, with a total of 100 units. The capacitance size is also calculated. If using mains rectification, it’s not very safe and quite troublesome, but the boost board can be utilized.
The white and blue pillars are copper standoffs with insulating sleeves for connection and fixation.
Remember to reinforce the bottom layer of the capacitor board. If the screws are not tightened, there will be a risk when the voltage reaches a certain level during charging.
Additionally, if the voltage drops from 450V to 400V with a working current of 50A, the duration can reach 10ms. Considering the voltage at 400V: 400V x 50A = 20kW, sustained for 10ms. The capacitors can output such a large power in a short time, making them very valuable.
