Source: InternetPublisher:兰博 Keywords: High power DC regulated power supply resistance and capacitance Updated: 2020/02/11
Calculation of resistance-capacitance protection parameters: In order to absorb the shutdown over-voltage and slow down the impact on SCR
, a resistance-capacitance absorption loop must be added. The resistance -capacitance absorption loop is shown in Figure 12-33. In the figure,
Lh is the leakage inductance of the transformer, which can dampen circuit oscillation and limit the thyristor turn-on
loss and current rise rate. According to the voltage and current capacity of the thyristor,
the empirical value of Rhcb can be found by looking up the table: R-80fl, Cb-0. 15pLF" The resistor power is
