When the thyristor is damaged and needs to be inspected and analyzed for its cause, the core can be removed from the cooling jacket, the core box can be opened, and the chip can be removed to observe the traces after the damage to determine the cause.
When a forward voltage is applied between the anode and cathode of a thyristor and no voltage is applied to the control electrode, the thyristor is in a forward blocking state.
Compared with parallel inverters, thyristor series inverters have more advantages:
Zener diodes are also a type of diode. When working normally, Zener diodes operate in the reverse breakdown region, where the current changes greatly while the voltage changes very little, thus achieving a voltage stabilization effect.
To make the thyristor conductive, the following conditions must be met
1. Overvoltage breakdown, 2. Overcurrent and overheating breakdown, 3. Overheating breakdown
