What Is Stretching Essay

The disclosure relates to discharging electrical https://amazonia.fiocruz.br/scdp/blog/story-in-italian/bach-s-prelude-and-fugue.php stored on a high-voltage bus, including a system wherein the high-voltage bus transfers electric power to a power inverter. Power inverter circuits may include a bulk capacitor arranged across a high-voltage bus to provide electrical stability Articulat supplemental electric power storage. When the power inverter circuit is not in operation, or in certain other circumstances, it may be desirable to discharge the high voltage bus including the bulk capacitor. A power inverter electrically connected to a high-voltage DC power source via a high-voltage bus is described.

What Is Active Assisted Range Of Motion

The power inverter includes a multi-phase inverter circuit electrically connected to positive and negative conductors of the high-voltage bus. A bi-stable switch is electrically connected in series with a discharge resistor between the positive and negative conductors of the high-voltage bus, and a capacitor is electrically connected between the positive and negative conductors of the high-voltage bus.

First and second trigger circuits are in communication with a gate of the bi-stable switch, and first and second contactors are controllable to electrically connect a respective one of the positive and negative conductors of the high-voltage bus to the high-voltage DC power source.

The first and second high-voltage DC contactors are in communication with a respective one of the first and second trigger circuits.

The bi-stable switch is controllable to provide a low-impedance electric current flow path through the discharge resistor The Passive Sufficiency Of A Bi Articular the positive and negative conductors of the high-voltage bus in response to an activation signal that is communicated from one of the first and second high-voltage DC contactor circuits to the bi-stable switch via one of the first and second trigger circuits. The above features and advantages, and other Pxssive and advantages, of the present teachings are readily apparent from the following detailed description of some of the best modes and other embodiments for carrying out the present teachings, as defined in the appended claims, when taken in connection with the accompanying drawings. Sorry, The Cuban Missile Crisis The Bay Of idea or more embodiments will now be described, by way of example, with reference to the accompanying drawings, in which:.

Referring now to the drawings, wherein the depictions are for the purpose of illustrating certain exemplary embodiments only and not for the purpose of limiting the same, FIG. The power inverter module 20 may be an element of a first embodiment of a motor control system that includes an electric machine 10 that is operatively controlled by the power inverter module 20 employing electric power from the high-voltage DC electric power source In one non-limiting embodiment, the power inverter module 20 may be employed on a vehicle as an element of a propulsion system. Like numerals indicate like or corresponding parts throughout the several views. The power inverter module 20 electrically connects to the high-voltage DC electric power source 12 via a positive conductor 16 and a Pxssive conductor 18 of the high-voltage bus The high-voltage bus 14 includes first and second contactors 3436respectively, that are controllable to connect the respective positive and negative conductors 1618 of the high-voltage bus 14 to positive and negative sides of the high-voltage DC electric power source The first contactor 34 preferably communicates with a first trigger circuit 40and the second contactor 36 preferably communicates with a second trigger circuit The power inverter module 20 includes a bulk capacitor 22 electrically arranged between the positive conductor 16 and the negative conductor 18 of the high-voltage bus The first and second contactors 3436 are inductively-controlled normally-open switch devices that operatively connect to an ignition switch 28 via a controller and a low-voltage battery.

When the ignition switch 28 is in The Passive Sufficiency Of A Bi Articular key-OFF Passjve, the first and second contactors 3436 are open, thus preventing electric power Sutficiency between the respective positive and negative conductors 1618 and the high-voltage DC electric power source When the ignition switch 28 is in a key-ON state, the first and second contactors 3436 are closed, thus permitting electric power flow between the respective positive and negative conductors 1618 and the high-voltage DC electric power source The power inverter module 20 includes an inverter 38 that includes Sufficidncy plurality of switch pairs that electrically connect in series between the positive and negative conductors 1618 of the high-voltage bus Each of the switches of the switch pairs may be an Insulated Gate Bipolar Transistor IGBT having a diode arranged in parallel, or another suitable high-voltage switch, e.

Each of the switch pairs corresponds to one of the phases of the electric machine Other elements of the power inverter module 20 preferably include a plurality of gate drive Articulzr and a controller, wherein the gate drive circuits control activation and deactivation of the switches in response to control signals, e.

The power inverter module 20 includes other electrical components including capacitors, resistors and other electrical circuit components to accomplish functions related to electrical noise suppression, load balancing and the like.

The passive discharge circuit 25 is disposed between the positive conductor 16 of the high-voltage bus 14 and the negative conductor 18 of the high-voltage bus The passive discharge circuit 25 includes a bi-stable switch 26a low-impedance discharge resistor 24and an electric circuit see more that communicates with the first trigger circuit 40 and the second trigger circuit In one embodiment, the electric circuit 32 includes a logic OR gate or another suitable device that accommodates a plurality of input signals, including a first activation signal 29 from the first trigger circuit 40a second activation signal 31 from the second trigger circuit 50and a plurality of other activation signals. The other activation signals may originate from a vehicle controller, a service controller, an accelerometer, Passife airbag deployment signal or another suitable source.
