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 Power Diode?Power DiodedefinitionBased on semiconductor PN, its on-off and off-off are completely determined by the voltage and current it undergoes in the main circuit, which can realize the function of positive on-off and reverse cutoff, and the power diode is an uncontrollable device.How Power Diodes workWhen the PN junction is applied with a forward voltage, that is, P→+, N→-, the external electric field is opposite to the internal electric field, and the diffusion motion is greate

The design and advantages of a novel light emitting diode (LED) bandwidth extension technique, based on the adoption of negative impedance converters (NICs), are discussed in the context of visible light communication systems. The design principles of the proposed negative impedance converter are introduced, with analytical derivations of the impedance frequency behaviour and the circuit performance frequency limitations. A two-transistor circuit is designed to generate a negative capacitance ov
