CAN Precharge

The WaveSculptor motor controller has 10,000µF of low-impedance capacitance across the DC bus input connections. An external precharge circuit is mandatory. When not driving a motor, the WaveSculptor does not draw any power from the DC bus. Therefore, to avoid any high voltages on the bus connector when it is unplugged, an external discharge circuit is recommended.

This product provides a method to implement these two requirements. It can be configured in multiple ways, depending on the performance, cost and weight optimisation you wish to make with your vehicle. Please refer to any relevant race or certification regulations when deciding what type of circuit or component values to use.

The CAN precharge controller communicates its status and measurement information on the CAN bus, and receives commands to precharge and discharge via the same network interface.
