The schematic diagram of frequency converter AC-DC-AC frequency conversion speed regulation, in which R0 plays a current limiting role, when R, S, TterminalWhen the power is turned on, R0 is connected to the circuit to limit the starting current. After a delay, the thyristor VT conducts, short circuiting R0 to avoid unnecessary losses. Rt is the energy consumption braking resistor. When the motor enters the power generation state during braking, the inverter charges the capacitor C in reverse. When the voltage of the DC circuit (the voltage on resistors R1 and R2) rises to a certain value, the pump circuit is used toswitchDevice Vb conducts, so that the electrical energy on capacitor C is consumed by resistor Rt.A silicon stack is a series connection of multiple diodes and then packaged.The interior of the high-voltage silicon stack is composed of multiple high-voltage rectifier diodes (silicon particles) connected in series. When detecting, a multimeter can be usedR×10kMeasure its forward and reverse resistance values. A normal high-voltage silicon stack has a forward resistance value greater than200kΩ, the reverse resistance value is infinite. If a certain resistance value is measured in both forward and reverse directions, it indicates that the high-voltage silicon stack has been soft breakdown damaged.
