Free QuoteFigure 1. Pre-charge Initial State In a high voltage system, a typical block diagram may consist of two high current contactors with a separate pre-charge contactor, and a DC link capacitor in parallel with a load (for example, traction inverter).
The pre-charge resistor failing due to over-heating then needs to be at least considered. In a battery the contactors are a switch that can be operated by the control system. They are essentially a relay. These contactors are designed to be able to break (switch off) the circuit under full load (maximum current and at maximum system voltage).
High voltage (HV) positive and negative contactors are used in this system to act as an emergency disconnect when the motor regulator fails. Without a pre-charge circuit, welding can occur within the contactor as it closes and there could be a brief arc resulting in pitting. Figure 1. Pre-charge Initial State
Pre-charge State call the pre-charge state. In the pre-charge state, the pre-charge contactor and the HV negative contactor are closed as shown in Figure 2. The DC link capacitor charges to nearly the same voltage as the voltage source.
In the pre-charge state, the pre-charge contactor and the HV negative contactor are closed as shown in Figure 2. The DC link capacitor charges to nearly the same voltage as the voltage source. After the pre-charge state, the pre-charge contactor opens and the HV positive contactor closes to drive the system or charge the battery.
