Latest Patents

Himavarsha holds a patent titled "Motor drive topologies for traction and charging in electrified vehicles." This patent describes a motor drive system that incorporates a DC source, such as a battery, and an inverter. The inverter features multiple phase drivers designed to switch current from the DC source to generate AC power at various output terminals. The system utilizes a hybrid of different solid-state switches, each with specific voltage ratings. Notably, the nine-switch inverter includes three phase drivers, which consist of high, low, and middle solid-state switches. The high and low switches are Si-MOSFETs rated at half the system's voltage, while Gallium Nitride (GaN) transistors are used for the middle switches, capable of handling the full rated voltage. Additionally, a delay driver synchronizes the timing between different solid-state switches, optimizing performance through near-state pulse-width modulation (NSPWM) to minimize switching losses.
