Abstract: A bi-directional DC-DC converter (201) and an on-board charger (101) with the bi-directional DC-DC converter (201) integrated into it are disclosed for converting a first voltage to a second voltage. The bi-directional DC-DC converter (201) includes a transformer (300b or 400b) for magnetically coupling a primary circuit (300a or 400a) receiving the first voltage on a primary side with a rectification circuit (300c or 400c) on a secondary side. Further, a high voltage power source (104) is connected to the rectification circuit (300c or 400c) for supplying a high voltage to one or more high voltage loads and a low voltage power source (202) is connected to the high voltage power source (104) through a secondary circuit (300d or 400d) for supplying a second voltage to one or more low voltage loads are disclosed. The bi-directional DC-DC converter functions in both stationary condition and running condition of a powered device.

Abstract: The present subject matter discloses a pre-charging system in a vehicle. The present subject matter particularly describes the system and method to reduce the effect of the inrush current due to the presence of capacitor load (304) in the circuit. A controller controls the duty cycle using a pulse width modulation (PWM) signal (310) to limit the peak current and preventing the contactor damage which can be caused due to the sudden inrush current.

Abstract: The present invention relates an electric machine of a vehicle (100), and more particularly, the present invention relates to a controller equipped with switches for the electric machine of a vehicle (100). The rotating magnetic field is created in steps of 60⁰ electrical angles, which results in rotor torque selected as a combination of 60⁰ of the torque versus angle waveform, which has a peak torque resulting in six repeated torque waveforms. By the present configuration, it is possible to increase the lowest torque of the output torque waveform, which in turn increases the average torque of the rotor and still keeping the peak torque same.

Abstract: The present subject matter discusses about the electric machine and core saturation sensing setup, and the method of detecting the core saturation. The present subject matter proposes that an auxiliary winding with at least one tooth is wound around at least one of the stator tooth along any one phase of the phases of the machine. The ends of the wire are given to the signal conditioning circuit which filters the signal from noises. The filtered signal is given to an ADC (analog to digital converter) pin of the controller to digitalize the signal value.

Abstract: The present subject matter provides electric machine (16) with an auxiliary coil (20) wound around a stator tooth and voltage induced in the auxiliary coil 5 (20) is used to control one or more switches (s101, s102) used for winding reconfiguration. The voltage induced in the coils depends on the speed of rotation for a given number of turns. To operate the reconfiguration through the switches (s101, s102), the voltage has to be above a threshold which is achieved above a rotational speed. The switches (s101, s102) for reconfiguration are arranged such 10 that they are normally in one configuration giving rise to standard motor speed- torque characteristics, and when energized gives rise to another winding configuration, resulting in changed motor characteristics. The voltage induced in the auxiliary coil (20) is used to operate the switches (s101, s102) which save energy and any controller modifications of the present vehicles.
