The invention provides a band-type brake power supply circuit, a band-type brake driver and an elevator band-type brake device.The band-type brake power supply circuit comprises a power supply main loop, a sampling circuit, a first protection circuit, a second protection circuit, a first signal output circuit and a second signal output circuit; the power supply main loop comprises a rectification circuit, a voltage conversion circuit, a first switch circuit and a second switch circuit, and when an abnormal condition occurs, the first protection circuit and the second protection circuit respectively trigger and output a first enable signal and a second enable signal; the first signal output circuit triggers to turn off the first switching circuit and the second switching circuit based on the first enable signal, and the second signal output circuit triggers to turn off the voltage conversion circuit based on the second enable signal, so that the power supply of the band-type brake is cut off, and the band-type brake is switched to a band-type braking state. The band-type brake power supply circuit does not need to be provided with a band-type brake, miniaturization of the band-type brake device is achieved, and the design cost is reduced.
本发明提出一种抱闸电源电路、抱闸驱动器和电梯抱闸装置,其中,抱闸电源电路包括电源主回路、采样电路、第一保护电路、第二保护电路、第一信号输出电路和第二信号输出电路,电源主回路包整流电路、电压转换电路、第一开关电路和第二开关电路,出现异常状况时,第一保护电路和第二保护电路分别触发输出第一使能信号和第二使能信号,第一信号输出电路基于第一使能信号触发关断第一开关电路和第二开关电路,第二信号输出电路基于第二使能信号触发关断电压转换电路,从而切断抱闸制动器的供电电源,抱闸制动器切换至抱闸制动状态,抱闸电源电路无需设置抱闸制动器,实现了抱闸装置的小型化以及降低了设计成本。
