What is a Schottky Diode?Schottky Diode definitionThe reverse recovery time is extremely short (can be as small as a few nanoseconds), the positive pilot voltage drop is only about 0.4V, and the rectification current can reach thousands of amps, which can be used as a switching diode and a low-voltage high-current rectifier diode.Schottky Diode structureIt is formed by connecting doped semiconductor regions (usually N-type) with metals such as gold, platinum, titanium, etc. The formation is not

What is a Fast Recovery Power Diode?Fast recovery power diode definitionSemiconductor diodes with good switching characteristics and short reverse recovery time are mainly used in switching power supplies, PWM pulse width modulators, frequency converters and other electronic circuits as high-frequency rectifier diodes, continuous current diodes or damping diodes.Fast recovery power diode performance characteristics The reverse recovery time is short The reverse recovery charge is smallDetection

What is a High Voltage Circuit Breaker?High Voltage Circuit Breaker definitionA type of circuit breaker used in power systems with a rated voltage of 35KV and above, used to cut or switch on loaded or unloaded circuits, as well as faulty circuits.High Voltage Circuit Breaker components Conductive part : responsible for the conduction of current ‌Insulation part : prevent electric shock accident ‌Operating mechanism : through the contact parting, ‌ closing action to realize the circuit to break a

What is the thermal effect of electric current?Definition of thermal effect of currentWhen the current passes through the resistance, the current does work and consumes electrical energy, generating heat.Calculation formulaQ=I^2 Rt I - The current passing through A conductor in amperes (A); R -- the resistance of the conductor, in ohms (Ω); t -- the time for the current to pass through the conductor, in seconds (s); Q - The heat generated by the current on the resistance, in joules (J)Apply Inca
