Energy accumulator emulator and method for emulation of an energy accumulator

Various aspects of the present disclosure are directed to energy accumulator emulators. In one embodiment, an energy accumulator emulator is disclosed including a DC-to-DC converter having a number of power switches, a control unit that calculates a reference current from electrical variables of the DC-to-DC converter, and a battery model connected to the control unit. The battery model receives and processes the reference current and communicates a referenced voltage to the control unit. The control unit includes a voltage controller that processes the reference voltage and controls a current, on the basis of which the control unit controls the power switches via switching pulses to control an output voltage. The energy accumulator emulator further includes a PPPC unit that is connected to the voltage controller. The PPPC unit provides a number of pulse patterns, selects a pulse pattern, and controls the power switches according to the selected pulse pattern.
