Abstract
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.
