Multi-Rate Commutation Of Motors

US Patent:
2003007, Apr 24, 2003
Filed:
Mar 18, 2002
Appl. No.:
10/101675
Inventors:
Jesus DelValle - Irvine CA, US
Prakash Kasturi - Rancho Santa Margarita CA, US
Adrian Nastase - Huntington Beach CA, US
International Classification:
H02P001/18
H02P003/08
H02P005/06
H02P007/06
H02K023/00
US Classification:
318/254000
Abstract:
A motor control system that determines a number of commutation values during each control cycle of the system. Determining a plurality of commutation values provides a system with a higher frequency of commutation updates without having to increase the speed of the control cycle. This allows for a smoother operation of a motor without having to increase the speed of the control system processor.

System And Method For Detecting The Presence And Type Of Capacitive Loads

US Patent:
2018011, Apr 26, 2018
Filed:
Dec 21, 2017
Appl. No.:
15/850349
Inventors:
- Irvine CA, US
Jesus Delvalle - Irvine CA, US
International Classification:
G01R 27/26
H02N 2/14
H01L 41/04
G01R 31/34
Abstract:
System and method for detecting the presence and type of capacitive load that may be coupled to a power driver. The system includes a detection circuit to determine the presence and type of load based on a measured characteristic of the load in response to a drive voltage. The characteristic may be the load capacitance as measured by the current flow between the driver and load. The circuit may include a differential amplifier to generate a current-related voltage, comparators to generate pulses when the voltage exceeds respective thresholds, registers to output logic levels in response to the comparators, and a microcontroller to make the determination based on the logic levels. Alternatively, the circuit includes a differential amplifier to generate a current-related voltage, a rectifier to rectify the voltage, a peak and hold circuit to hold the peak voltage, an ADC to digitize the peak voltage, and a microcontroller to make its determination based on the digitized voltage.
