Patent number: 10840833Abstract: A commutation circuit includes a coil connected to an H bridge, the H bridge including four main switches for reversing polarity and a resulting coil current in the coil. The commutation circuit further includes a voltage source configured to generate a bypass current, and at least one auxiliary switch for controlling the bypass current to thereby decrease a switch current through at least one of the main switches. By generating an appropriate bypass current with help of a voltage source, a switch current through a desired main switch in a leading state can be decreased and eventually brought to zero. Zero current in its turn enables the use of thyristors as main switches as it results in the thyristors to be turned off automatically. Furthermore, decreased switch current at the switching moment reduces switching losses even in different types of switches such as GTOs and IGBTs.Type: GrantFiled: March 31, 2015Date of Patent: November 17, 2020Assignee: ABB Schweiz AGInventors: Sjoerd Bosga, Veli-Matti Leppanen, Mehanathan Pathmanathan, Robert Chin, Yujing Liu

Patent number: 8997214Abstract: In order to create and access a secure storage account in a non-volatile memory device, an account identification value is calculated. A memory identification value is read from a first non-volatile memory device. The memory identification value and the account identification value are transmitted to a second non-volatile memory device, and a calculated credential is received. A command is transmitted to create a secure storage account in the first non-volatile memory device, where the command contains the credential and the account identification value. To access the account, a sequence is transmitted, containing the account identification value and a value based on the credential. A secure storage system contains a first non-volatile memory device that stores a memory identification value and contains a secure partition accessible using a credential, a second non-volatile memory device that can compute the credential, and a host adapted to create and access the secure partition.Type: GrantFiled: February 21, 2012Date of Patent: March 31, 2015Assignee: SanDisk Technologies Inc.Inventors: Po Yuan, Javier Canis Robles, Mei Yan, Fabrice Jogand-Coulomb, Ahmet Altay, Bahman Qawami, Patricia Dwyer, Robert Chin-Tse Chang, Oktay Rasizade, Farshid Sabet-Sharghi
