DSP Control Improves Inverter Performance and Density
Standard unipolar PWM voltage modulation is used because it offers the advantage of effectively doubling the switching frequency of the inverter voltage.

Q: Do we need DSP innovations between generations, or can we just rely on Moore''s Law to do the work for us? More accurately this is Dennard Scaling for power
In the figure, AH is the signal used to drive the high-side power device of inverter leg A and AL is used to drive the low-side power device. The duty cycle effectively adjusts the average voltage
Unlock the full potential of digital signal processing in power electronics with our in-depth guide, covering key concepts, applications, and best practices.
Because 16-bit, fixed point DSPs integrate numerous functions such as PWM channels, ADCs, CAN interfaces, memory, serial ports, event timers, and encoder interfaces, they can be used
This chapter deals with the DSP control of three-phase voltage source inverters. A study on a 10-kW grid-connected photovoltaic inverter with two control options, namely, the α
The proposed DSP-based grid-tied inverter is an option to fill this company''s need for state-of-the-art inverter controls. In particular, the new technology''s design might be readily adapted to
In this paper a modified space vector pulse width modulation (SVPWM) technique is proposed which will maintain the quality of the ac output of the inverter, regardless of the
The efficiency and level of integration of a DSP is crucial in low-power systems. An efficient architecture enables the DSP to finish calculations quicker, allowing it to remain in low
Classical PI control with grid voltage feed-forward is commonly used for current-controlled inverters. In this control, the error between actual and reference current is fed to a PI controller.
