The half bridge is used in some switched-mode power supplies that use synchronous rectifiers and in switching amplifiers. The half-H bridge type is commonly abbreviated to "Half-H" to distinguish it from full ("Full-H") H-bridges. Another common variation, adding a third 'leg' to the bridge, creates a three-phase inverter.
Half-Bridge can refer to: A single-direction configuration of an H-Bridge motor controller; A form of DC to DC converter switched-mode power supply. One of a pair of devices that connect to perform the Bridging (networking) function of a computer network
bridge rectifier containing four (1-phase) or six (3-phase) diodes; half bridge [1] (inverter leg, with two switches and their corresponding antiparallel diodes) H-Bridge (four switches and the corresponding antiparallel diodes) boost or power factor correction (one (or two) switches with one (or two) high frequency rectifying diodes)
A bootstrap circuit is often used in each half-bridge of an all-N-MOSFET H-bridge. When the low-side N-FET is on, current from the power rail (V+) flows through the bootstrap diode and charges the bootstrap capacitor through that low-side N-FET.
As with single-phase rectifiers, three-phase rectifiers can take the form of a half-wave circuit, a full-wave circuit using a center-tapped transformer, or a full-wave bridge circuit. Thyristors are commonly used in place of diodes to create a circuit that can regulate the output voltage. Many devices that provide direct current actually ...
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
With the ability to place high-voltage circuitry (in a ‘well’ formed by polysilicon rings), that can ‘float’ 600 V or 1200 V, on the same silicon away from the rest of the low-voltage circuitry, high-side power MOSFETs or IGBTs exist in many popular off-line circuit topologies such as buck, synchronous boost, half-bridge, full-bridge ...
A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...
