All devices and equipment must pass the oldest EMC standard which is the flicker-test. This standard defines how an equipment is allowed to draw power from the network without generating voltage fluctuations which would disturb lightning.
In most modern devices flicker is controlled by software (e.g. switching on and off of a heater), also hardware can be affected, e.g. if performance specification and flicker standard can only be reached through optimization of the form of the switching transient.

The package contains the flickermeter simulator and several examples:
flicker_sim
- Flickermeter Simulator according IEC 61000-4-15 Edition 2.0
Helper functions:
power_to_line_voltage
- Generate line voltage signal from a vector of power samples
power_to_phase_control_line_voltage
- Generate phase controlled line voltage signal
Examples:
example_phase_control
- Example investigating phase control to reduce flicker
example_half_wave_control
- Example investigating half wave control to reduce flicker
example_heater
- Example using measured data of a heater control system
heater_1.mat .. heater_4.mat
- Input data for example_heater
example_testbench_50Hz / example_testbench_60Hz
- Test scripts to check performance (accuracy) of flicker_sim
example_testbench_230V_sin / example_testbench_120V_sin
- Test scripts to check performance (accuracy) of flicker_sim
example_testbench_rectangular_voltage_changes_with_duty_ratio
- Test script to check performance (accuracy) of flicker_sim
