Choose a larger capacitor (such as 100nF) as capacitor C
Adopting RCD absorption, the absorbed energy includes two parts:
The reverse recovery of rectifier tubes only occurs in continuous operation mode
The rectifier circuit shown in Figure 1 has a broken rectifier bridge and smoke from the filtering capacitor during use.
ROHM Corporation has recently launched an ultra small rectifier diode RR255M-400.
Variable capacitance diode, also known as variable capacitance diode
