Title: Åke Christensson: Inventor of a Synchronized Pulse Width Modulation System

Introduction

Åke Christensson is an inventor associated with Västerås, Sweden. His patent work includes a system for synchronizing pulse width modulation across multiple control modules. He is credited with 1 patent.

Latest Patents

Christensson’s listed patent is “Pulse width modulation system and a method in relation thereto.” The invention describes a modular system with a master control board and multiple slave control boards. A timer on the master board generates a clock signal, while each slave board uses timer information received over a communication bus to determine a fictive master timer and synchronize its own timer rate.

The timer information includes an offset between the master and slave timers. Each slave board applies this offset when controlling its pulse-width-modulated phase outputs, positioning those signals in relation to the fictive master timer. This approach coordinates timing across the system’s modules.

Career Highlights

Christensson’s listed company affiliations include Alstom Holdings and Bombardier Transportation GmbH. His patent reflects work on control-system timing and coordination in modular applications.

Collaborations

His listed coworkers include Lucas Lodesten and Torbjörn Trostén.

Conclusion

Åke Christensson’s patent describes a method for synchronizing pulse-width-modulated outputs across master and slave control boards, highlighting his contribution to modular control-system technology.
