This from a discussion in the Digital Power Electronics Control Group on Linkedin ‘I was wondering if you could explain what you mean by “…ensuring that the PWM does not latch at the switching speed (very important for wide bandwidth)”. Isn’t the PWM comparator by nature a latch? Are you implying for best performance one […]

How can I look at my digital signals in my power controller? One of the big issues when working on digital control of power electronics is being able to look at the digital signals inside your controller. In order to see what is going on inside the control the digital signals need to be brought out […]

In a recent discussion we were asked about the migration path from MCU/DSP to FPGA. “I am probably not alone when I use MCU/DSP devices to implement control algorithms, protection, logic etc to control the power hardware, using code such as ASM, C or C++, but want the advantages of FPGA. What suggestions do you […]

One question which is commonly asked is “how do I represent fractional numbers on my fixed-point MCU, DSP or FPGA?” One of the best solutions to this is use of the Q number system. The Q number system is a fixed point system where the available bits are divided amongst the integer bits (those to […]

This article was originally published in 2010. It is part of the ELMG redux series of articles that will be republished over the summer. These articles cover subjects in and around digital control of power electronics. Redux – Safety Critical Digital Control – Planes in Fog Just before Christmas 2006 I spent sometime (24 hours) in Copenhagen […]
