| Abstract: | Pulse release is widely used in circuit breakers to realize protection rapidity. The characteristics of low-end switching circuits based on SCR, IGBT or POWER MOSFET are analyzed in the paper, and three types of low-end switching circuits in pulse release are simulated. The simulation results show that the low-end switching circuits using paralleled POWER MOSFET can control tripping on/off of the pulse trip unit quickly, safely and reliably, so that the fast output of the pulse release can be realized. |
