One-way energy consumption braking circuit b

  The circuit is shown in Figure 3 133. Figure 3-133 The energy consumption braking of the three circuits (a), (b) and (c) are all
controlled manually (button). Among them, the energy-consuming braking DC power supply in Figures (a) and (b) is obtained by step-down transformer and bridge rectifier rectification, and the energy-consuming braking
win-current power supply in Figure (c) is obtained by a diode. Their working principles are similar. But the former has better braking effect than the latter . This kind of circuit is often used in situations below 7.5kW with high braking requirements. For motors with larger power, the DC power supply for braking should use a three-phase rectifier circuit.
