| 7301313 | Multiple voltage regulators for use with a single load Multiple voltage regulators for use with a single load. The present invention allows power to be supplied to an electrical load using multiple voltage regulators based on the operating environment of the load. In one embodiment, a primary voltage regulator that is b... | 11/27/2007 |
| 7005829 | System for precharging a DC link in a variable speed drive A variable speed drive with a converter that is controllable to precharge a DC link is provided. The variable speed drive also includes an inverter. The converter converts a fixed line frequency, fixed line voltage AC power from an AC power source into DC power. The... | 02/28/2006 |
| 7005609 | Apparatus for a welding machine having a cooling assembly mounted to a mid-plane baffle for improved cooling within the welding machine A mid-plane baffle or plate having a fan mounted thereto to dissipate heat within a welding machine is provided. By centrally positioning a baffle and mounting a circulating fan thereto, cooling efficiency is improved thereby enabling more direct cooling of the inte... | 02/28/2006 |
| 6992906 | Synthetic rectifiers A synthetic rectifier comprises a MOSFET and a control circuit to turn the MOSFET off and on as a synchronous rectifier. The control circuit senses the current through the synthetic rectifier, and in particular is responsive to the rate of decrease of the current so... | 01/31/2006 |
| 6956748 | Switching power supply apparatus A switching power supply apparatus which has an input power source; a transformer having a primary winding, a secondary winding, an input winding and a magnetic flux canceling winding being connected to the secondary winding in series; a main switch for switching an... | 10/18/2005 |
| 6879128 | Method and apparatus for independently controlling each phase of a multi-phase step motor The current in each phase of a multi-phase step motor is monitored and the excess phase current above the set point current, as required on a cycle-by-cycle PWM basis, is reduced thereby bringing each phase current down to the set point. The PWM frequency is automat... | 04/12/2005 |
| 5831807 | Overload and short circuit protection device for a power semiconductor circuit An overcurrent and short circuit protection device for a power semiconductor component is responsive to output current signals representing the actual output current(s) of the semiconductor component. A short-circuit window comparator receives the output ... | 11/03/1998 |
| 3982173 | AC-DC voltage regulator AC-DC voltage regulation is achieved utilizing, among other components, a series pass control element which is serially connected to a detector and filter output stage and between circuit input terminals and an output load. A rectified input voltage is ap... | 09/21/1976 |
