Abstract

An amplifier is provided. The amplifier comprises an H-bridge with two halves. A capacitor and two inductors are coupled to the H-bridge. Each inductor, a half of the H-bridge, and the capacitor are configured as a boost converter.

Claims (14)

1. An amplifier, comprising:

an H-bridge that comprises a first switch, a second switch, a third switch, and a fourth switch;

a capacitor coupled to the H-bridge;

a first inductor coupled to the H-bridge, wherein the first inductor, the first and second switches, and the capacitor are configured as a first boost converter;

a second inductor coupled to the H-Bridge, wherein the second inductor, the third and fourth switches, and the capacitor are configured as a second boost converter;

a first set of delta-configured inductors coupled to the first and second switches; and

a second set of delta-configured inductors coupled to the first set of delta-coupled inductors and the third and fourth switches.

2. The amplifier of claim 1 , wherein the H-bridge further comprises:

a first magnetic coupling that couples the first and second set of delta-configured inductors; and

a second magnetic coupling that couples the first and second set of delta-configured inductors.

3. An amplifier, comprising:

a half H-bridge that comprises a first switch, a second switch, and a set of delta-configured inductors, the set of delta-configured inductors being coupled to the first and second switches;

a capacitor coupled to the half H-bridge; and

an inductor coupled to the half H-bridge, the inductor, the first and second switches, and the capacitor being configured as a boost converter.
