Abstract

See full text

A battery-powered load control device (e.g., a motorized window treatment) is able to supply a pulse-width modulated current to an electrical load (e.g., a motor) while conducting a substantially DC battery current from a battery powering the motorized window treatment. The motorized window treatment includes a motor drive circuit for driving the motor with a pulse-width modulated signal to adjust the rotational speed of the motor, such that the motor conducts the pulse-with modulated current. The motorized window treatment also has an input circuit coupled between the battery and the H-bridge drive circuit. The input circuit has an output for conducting the pulse-width modulated load current, and conducts the substantially DC battery current from the battery. The input circuit may comprise, for example, a passive filter circuit (such as an inductor-capacitor filter) or an active circuit (such as a power converter).
