“…In [17][18][19], the theoretical THD of the input current is reduced from 15.2% to approximately 7.6%, and the experimental results show a decrease from about 10% to 4%, suppressing the (12k±1)-th harmonics. In [20][21][22], the theoretical THD of the input current is reduced from 15.2% to about 5%, with experimental results around 3%, effectively suppressing most of the (12k±1)-th and (24k±1)-th harmonics. While passive harmonic suppression methods effectively suppress most of the rectifier harmonics, high-order harmonics remain unaddressed, making it challenging to reduce the THD of input currents below 3%.…”

“…The harmonic suppression circuit comprises an AST, two diodes, and multiple switches. In comparison to the passive harmonic suppression methods in [17][18][19][20][21][22] and the active harmonic suppression methods in [23][24][25], the harmonic suppression ability is significantly enhanced. Unlike the active methods in [23][24][25], the operating frequency is decreased by tens or even hundreds of times, resulting in a reduction of high-order harmonics and contributing to the mitigation of load voltage ripple.…”

“…To ensure three-phase balance and enhance input power quality, various DC link harmonic suppression methods are proposed, primarily categorized as passive, active, and hybrid methods. The passive methods in [17][18][19][20][21][22] typically involve an auxiliary single transformer (AST) and multiple diodes for harmonic suppression. In [17][18][19], the theoretical THD of the input current is reduced from 15.2% to approximately 7.6%, and the experimental results show a decrease from about 10% to 4%, suppressing the (12k±1)-th harmonics.…”

To enhance the power quality of the accelerator power supply system, a series-connected multi-pulse rectifier (MPR) is proposed, utilizing a novel hybrid harmonic suppression method. The operating modes are analyzed by considering the topology of the rectifier. The turn ratio and switching angle are determined based on the operating mode, with the goal of minimizing the total harmonic distortion (THD) of the input voltage. To further study the performance of the rectifier and lay a foundation for its application of accelerator power supply system, the relationship among the amplitude and frequency of input voltage, the input inductors the load and the output voltage is researched. Testing results show that after using the proposed harmonic suppression method, the capacity of the injection transformer is only about 2% of the output power, the THD values of the input voltages and currents reduce significantly, the output voltage has low ripple with different loads.

“…A single-phase bridge rectifier and a single-phase full-wave rectifier are used to achieve voltage harmonic injection, which eventually multiplies the rectifier pulse number from 12 to 24. However, considering that the harmonic content of the 24-pulse rectifiers is still too high, various series 36-pulse rectifiers with dual passive harmonic injection have been proposed in [19]- [21]. The dual passive injection scheme can effectively suppress harmonics even further, but it requires two injection transformers, which increases the magnetic device share of the system and leads to increased hysteresis and eddy current losses, lowering power conversion efficiency.…”

In this study, a new 36‐pulse rectifier with a hybrid DC‐reinjection circuit is proposed. It multiplies the AC‐side input voltage steps from 12 to 36 using a hybrid auxiliary circuit for voltage and current modulation. Both the AC and DC side harmonics of the rectifier system are efficiently suppressed when combined with filter capacitors at DC side. Only 2 more diodes and an IGBT are used in the proposed approach for constituting the injection circuit. The cascaded structure of rectifier bridges allows for significant voltage gain, making it appropriate for high power output rectification applications. The proposed 12‐pulse rectifier's phase shifting structure and 36‐pulse rectifier's operational theory are introduced. The injection transformer's turn ratio and the IGBT's conduction angle are both designed to have the lowest possible harmonic distortion of the voltage at AC side. Analyses are done on the rectifier's impedance matching feature and energy loss of IGBT. The operating performance of the rectifier is assessed when the active switch fails. With the help of a 1.8 kW prototype and a HIL system based on Starsim, the theoretical portion is confirmed. The results of the simulation and experiments support the effectiveness of the hybrid voltage harmonic injection method studied.
