“…Voltage ripple destabilizes the power supply during the commutation interval. 7,23 The fundamental frequency of the voltage ripple is the same as the switching frequency of the dc-dc converter. [23][24][25][26][27] In addition, various multiple switching frequency components are superimposed with the voltage ripple named as switching frequency harmonics (SFH).…”

“…24 The voltage ripple results in unwanted speed regulation, unexpected mechanical vibration, and unwanted audible sound. 7,23 It also affects the accuracy and rotor position (hall sensors) of the BLDCM drive. To overcome these limitations, the conventional active stabilization technique based on LPF has been used.…”

“…Therefore, the electromagnetic torque contains significant amount of torque ripple, which causes abnormal vibration, unwanted speed regulation, and audible noise. 7 Thus, a variety of control techniques have been introduced for efficient mitigation of current ripple or torque pulsation. In 180 0 and 120 0 electrical modes of the VSI, the cause of current ripple and their effect on electromagnetic torque during the commutation period are investigated in Reference 8.…”

Summary Reduction of commutation current ripple (CCR) in the brushless direct current motor (BLDCM) drive using dc‐dc converter based topologies is achieving widespread popularity. However, undesired alternating current (AC) components are presented in the dc‐link voltage (DCLV) across the capacitor of the dc‐dc converter, which leads to a destabilization of the power supply during the commutation interval. In addition, unwanted audible noise and speed regulation occur which deteriorates the motor performance. In order to encounter these issues, different conventional compensation techniques based on the low‐pass filter (LPF) has been proposed. However, the LPF requires a close relation between dynamic coupling and active compensation. In view of the limitation, this paper proposes a notch‐filter to stabilize the DCLV. Performance of the notch‐filter is tested on a configuration of the BLDCM based on the front‐end zeta (FEZ) converter and DCLV selector circuit. The notch‐filter is used to stabilize the DCLV, whereas the DCLV selector circuit is employed to draw the regulated voltage drawn from the FEZ converter. Simulation and experimental results verify the effectiveness of the proposed control scheme for the BLDCM drive. The simulation and experimental results clearly reveal that the notch‐filter along with FEZ converter effectively stabilized the DCLV and alleviate the CCR.

“…The load converters are generally controlled by a high bandwidth regulator. Therefore, constant power loads (CPLs) occur, destructing the stability and even making the system unstable [5][6][7][8][9][10]. Besides, some special converters, such as bidirectional dc (bi-dc) converter, is influenced by CPLs and right-half-plane (RHP) zero.…”

The poor damping of bidirectional dc (bi-dc) converter caused by constant power load makes power system prone to oscillation, and non-minimum phase characteristic also jeopardises voltage stability. To solve these challenges, the interconnection and damping assignment passivity-based control (IDA-PBC) is utilised to improve transient response. The influences of the right-half-plane (RHP) zero on the stability margin and controller design are illustrated by zero dynamics analysis. Then the port-controlled Hamiltonian modelling is used to obtain the IDA-PBC control law, which is suitable to the bi-dc converter and independent of the operation mode. The system dissipation property is modified, and thus the desired damping is injected to smooth the transient voltage. To remove the voltage error caused by RHP zero and adjust the damping ratio, an energy controller with an adjustment factor is introduced. Besides, a virtual circuit is established to explain the physical meaning of the control parameter, and the parameter design method is given. Passivity analysis assesses the controller performance. Simulation results are analysed and compared with other control strategies to test the proposed IDA-PBC strategy.
