SWITCHING AMPLIFIER CIRCUITRY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056039 titled 'SWITCHING AMPLIFIER CIRCUITRY

Simplified Explanation

The patent application describes switching amplifier circuitry for driving an inductive load, which includes modulator circuitry and output stage circuitry. The circuitry is designed to adjust the switching frequency of the modulator circuitry over a predetermined range of frequencies while outputting a modulated signal that causes ripple current in the load. It also monitors the power of the circuitry as the switching frequency is adjusted and selects an operational switching frequency within the predetermined range at which the monitored power meets a predefined criterion.

• The switching amplifier circuitry adjusts the switching frequency of the modulator circuitry to optimize power efficiency.
• The circuitry monitors the power consumption as the switching frequency is adjusted to ensure it meets a predefined criterion.
• By selecting an operational switching frequency within the predetermined range, the circuitry can drive the inductive load efficiently and effectively.

Original Abstract Submitted

switching amplifier circuitry for driving an inductive load, the switching amplifier circuitry comprising modulator circuitry and output stage circuitry, wherein the switching amplifier circuitry is configured to: while the modulator circuitry is outputting a modulated output signal that gives rise to ripple current in the load: adjust a switching frequency of the modulator circuitry over a predetermined range of frequencies; monitor a power of the switching amplifier circuitry as the switching frequency is adjusted over the predetermined range of frequencies; and select, as an operational switching frequency for the modulator circuitry, a frequency within the predetermined range of frequencies at which the monitored power meets a predefined criterion.
