Method and apparatus for single-path control and monitoring of an H-bridge
First Claim
1. An apparatus for controlling and monitoring an H-bridge via a single communication path, comprising:
- a first control and monitor module coupled to a first switch within the H-bridge; and
a first pulse transformer coupled to a first control signal to the first control and monitor module, wherein the first control and monitor module (i) generates, based on the first control signal, a first driver signal for operating a first switch of the H-bridge during DC/AC power conversion, (ii) monitors at least a portion of the H-bridge for at least one fault, and (iii) communicates, upon detecting the at least one fault, a first fault indication to a main controller of the H-bridge via the first pulse transformer.

Abstract
A method and apparatus for controlling and monitoring an H-bridge via a single communication path. The apparatus comprises a first control and monitor module coupled to a first switch within the H-bridge; and a first pulse transformer coupled to a first control signal to the first control and monitor module, wherein the first control and monitor module (i) generates, based on the first control signal, a first driver signal for operating a first switch of the H-bridge during DC/AC power conversion, (ii) monitors at least a portion of the H-bridge for at least one fault, and (iii) communicates, upon detecting the at least one fault, a first fault indication to a main controller of the H-bridge via the first pulse transformer.

8. A method for controlling and monitoring an H-bridge via a single communication path, comprising:
-
transmitting, via a first pulse transformer, a first control signal; generating, based on the first control signal, a first driver signal for operating a first switch within an H-bridge during DC/AC power conversion; monitoring at least a portion of the H-bridge for at least one fault during the DC/AC power conversion; and communicating, upon detecting the at least one fault, a first fault indication to a main controller of the H-bridge via the first pulse transformer. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for converting DC power to AC power, comprising:
-
an H-bridge, comprising a first, a second, a third, and a fourth switch, wherein the first switch is coupled to a first control and monitor module, the second switch is coupled to a second control and monitor module, the third switch is coupled to a third control and monitor module, and the fourth switch is coupled to a fourth control and monitor module; a first pulse transformer coupled to a first control signal to the first and the third control and monitor modules; and a second pulse transformer coupled to a second control signal to the second and the fourth control and monitor modules; wherein (A) the first control and monitor module (i) generates, based on the first control signal, a first driver signal for operating the first switch during DC/AC power conversion, (ii) monitors at least a first portion of the H-bridge for a first fault, and (iii) upon detecting the first fault, communicates a first fault indication to a main controller via the first pulse transformer; (B) the second control and monitor module (i) generates, based on the second control signal, a second driver signal for operating the second switch during the DC/AC power conversion, (ii) monitors at least a second portion of the H-bridge for a second fault, and (iii) upon detecting the second fault, communicates a second fault indication to the main controller via the second pulse transformer; (C) the third control and monitor module (i) generates, based on the first control signal, a third driver signal for operating the third switch during the DC/AC power conversion, (ii) monitors at least a third portion of the H-bridge for a third fault, and (iii) upon detecting the third fault, communicates a third fault indication to the main controller via the first pulse transformer; and (D) the fourth control and monitor module (i) generates, based on the second control signal, a fourth driver signal for operating the fourth switch during the DC/AC power conversion, (ii) monitors at least a fourth portion of the H-bridge for a fourth fault, and (iii) upon detecting the fourth fault, communicates a fourth fault indication to the main controller via the second pulse transformer. - View Dependent Claims (16, 17, 18, 19)
