Voltage stabilization using zener diodes is well known to many, and the main stabilization element in circuits is the zener diode. Various radio components with threshold properties can serve as zener diodes. However, sometimes components not originally designed for this purpose, such as transistors and neon bulbs, are used as stabilizers. The essence of stabilization using threshold elements is that they pass current when a critical voltage is reached. It is the current flowing through the zener diode that stabilizes the voltage in the circuit. This is where paradoxes and forbidden riddles arise. A weak zener diode can easily fail when passing large currents, but the current and stabilization power can be increased by using a circuit with a transistor designed for threshold stabilization currents. I often encounter a solution to increase the stabilization current power in circuits published and described on amateur radio websites using zener diodes connected in parallel. Logically, a parallel connection increases the power of the stabilization circuit, BUT in practice, this is fundamentally incorrect. Yes, you can connect zener diodes IN SERIES, thereby increasing the stabilization voltage, but you CANNOT connect them in parallel! A simple experiment with neon lamps connected in a simplified PARALLEL circuit shows that when the specified stabilization voltage is exceeded, current will flow only through one threshold element, while the other will simply "rest." As a result, the circuit will work for a while, but at a certain point, one of the zener diodes will simply burn out and short-circuit the power supply. Conclusion: Connecting zener diodes in parallel is strictly PROHIBITED! #prohibitedcircuit #stabilizationcircuit #parallelzenerdiodes
