Working principle of fast recovery diode circuit

A fast recovery diode is a semiconductor apparatus with quick recovery characteristics and high efficiency. In the circuit, when the forward voltage is applied to both ends of the fast recovery diode, the diode conducts, and the current forms a loop through the diode, resistor, load and ground. The diode is in a low resistance state, allowing large currents to pass. When the reverse voltage is applied passing the diode, the diode is turned off, and the capacitor begins to discharge, providing continuous current to the load. The diode is in a high resistance state, limiting the current flow.

Advantages of fast recovery diode circuit

1. Fast recovery characteristics: Fast recovery diodes have a short recovery time, which can effectively reduce the reverse recovery current peak and drop time and improve circuit efficiency.

2. Superior high-frequency performance: Due to its excellent electrical performance, fast recovery diodes can reduce the rectifier circuit's power loss and improve its stability.

3. Good high-temperature characteristics: Some fast recovery diodes have a high operating temperature range, allowing them to perform well in high-temperature environments.

Selection of fast recovery diodes

Selecting the appropriate fast recovery diode is critical to circuit performance. Here are some suggestions:

1.Selection of withstand voltage value: Select an appropriate fast recovery diode fight voltage value based on the highest voltage value that may appear in the actual circuit； this helps ensure that the diode is not damaged by overvoltage when the course is operating correctly.

2.Rated current selection: Select the appropriate rated current of the fast recovery diode based on the maximum current value that may occur in the circuit; this helps ensure that the diode can safely conduct current when the course is operating correctly.

3.Recovery time considerations: Choose fast recovery diodes with shorter recovery times to reduce power loss and improve circuit efficiency. A quicker recovery time means the diode can complete the state transition faster, réduire la perte de puissance.
