Sub-cycle Averaging

Note

Sub-cycle averaging is available for all components in the Power Modules library section and for selected components in the Nanostep library section.

Sub-cycle averaging is an established modeling approach for power electronic converters that enables an accurate representation of switching behavior while maintaining computational efficiency. This is particularly relevant for C code generation and real-time simulations. Sub-cycle averaging consists of two main ingredients:

• An averaged duty-cycle signal with values between \(0\) and \(1\), obtained by averaging the input switching signal over an interval equal to the model discretization step size. In real-time simulations, these average values can be obtained by sampling PWM signals at each FPGA clock cycle of the real-time simulator, which is typically in the range of a few nanoseconds. Even with high switching frequencies and simulation steps much larger than the FPGA clock cycle, the resulting phase current remains accurate because the applied volt-seconds of the averaged signals correspond to the volt-seconds of the original PWM signals.

• A converter Power Module consisting of controlled current and voltage sources and a diode pair. The controlled sources are driven by the averaged duty-cycle signal, and the diode pair is required to simulate natural commutation and discontinuous conduction mode. Depending on the direction of the phase current, either the lower or the upper diode conducts, applying the corresponding phase voltage and DC current.

The main limitation of sub-cycle averaging is the inaccuracy caused by zero crossings of the phase current. As the direction of the phase current is determined only once per simulation step, slightly incorrect volt-seconds may be applied during the step in which the current crosses zero or enters DCM.

Nanostep Description

Nanostep converter modules are primarily intended for real-time simulations on the RT Box. The Nanostep solver incorporates the switching network and energy storage elements of the converter. Gate signal sampling, inductor current integration, and current zero-crossing detection occur at the FPGA clock cycle, typically in the range of a few nanoseconds. This makes the Nanostep solver suitable for converters in which the current direction changes frequently, especially resonant DC/DC converters and high-frequency converter topologies.

Some Nanostep components also provide a Sub-cycle average configuration, as described in Sub-cycle Averaging. In this configuration, generated code for real-time simulation on the RT Box runs on the CPU or FlexArray solver.
