PWM modulators are electronic devices used for controlling power delivery, commonly employed in industries such as automotive, industrial automation, and renewable energy. While PWM (Pulse Width Modulation) technology itself is not a brand but a method, several companies manufacture PWM modulators under their own brand names. For example, Texas Instruments (USA), Infineon Technologies (Germany), and STMicroelectronics (Switzerland) produce PWM modulators as part of their product portfolios. These devices are integral to applications like motor control, power supplies, and LED lighting, offering precision and efficiency in energy management. Leading industrial suppliers like Radwell and Grainger often distribute PWM modulators from these and other reputable manufacturers.
