Variable-speed-drive system for a grid blower
First Claim
1. A drive system for a grid blower of a vehicle comprising:
- an electrical bus;
a grid of resistive elements connected to the electrical bus, the grid of resistive elements configured to thermally dissipate electrical power generated by a braking operation of the vehicle, the electrical power being transmitted on the electrical bus to the grid of resistive elements;
an electrical power modulation device configured to modify electrical power received from the electrical bus, an input of the electrical power modulation device connected across at least one resistive element of the grid of resistive elements; and
a grid blower motor coupled to an output of the electrical power modulation device, wherein a speed of the grid blower motor varies based on the electrical power that has been modified by the electrical power modulation device.
