The high-voltage-resistant and non-inductive design enables various circuit designs. Our discharge resistors are characterized by a compact and lightweight design, which also allows mounting on printed circuit boards.
Our DIScharge resistors require a heat sink connection to ensure the optimal heat dissipation. This is crucial to provide the prom-ised resistor power. We offer power resistors with or without Most of our resistor housing capabilities offer plenty of room to add more functions. We are happy to fulfill your specific require-ments for the product.
A leading luxury sports car manufacturer worked with Miba to develop discharge resistors for its electric vehicles. The manufacturer was looking for a solution with high energy capacity and customizable specifications. Together, they created a product that improved the safety and reliability of the luxury e-sports car's electrical system.
PREcharge resistors are typically used in the battery junction box to limit the charging current of the DC-Link capacitor. The PREcharge resistor must withstand the high energy pulse up to 1000 volts. Miba PREcharge resistors can withstand this single pulse event without heat sink. The products are designed and
To achieve this voltage level, it is possible to short-circuit the IGBTs of the inverter, transfer energy to the elec-tric motor or use power resistors. Power resistors are the safest way to discharge, especially after a crash event. The important IGBTs are not additionally stressed by the discharge.
IGBTs are not additionally stressed by the discharge. When dis-charging, a distinction is made between active and passive dis-charging. With active discharging, there is an actively connected power resistor to bring the voltage below 60 volts. Passive dis-charging is carried out with power resistors, that are permanently connected to HV+ and HV-.

Online Services Email ContactIf it helps, the time constant for an RC circuit is 1/RC. So the voltage on the cap is given by V= V0•exp(-t/RC). This assumes all the discharge current is going through the resistor. If you''re using the 15µF cap and a 1MΩ resistor, the time constant is 15sec^-1. So the voltage would drop from, say, 100V to 37V in 15 seconds.
