รายการ Improved Line Imbalance of Single-Switch Converter by Double - Switch Converter for Common-Mode Noise Reduction(EECON2007, 2550-10-25) Boonpirom NimitThis paper aims to improve the system imbalance of the single - switch converters by employing the double -switch converter. The main objective is to analyze the cause of common mode noise generating in case of system imbalance and employing the double-switch converter for the common mode noise reduction. As the results, the ringing voltage and stress voltage of switching device are reduced. Finally, the experimental results in DC motor drive show the effectively improvement both time domain and frequency domain.รายการ A Study on the System Imbalance of the Single-Switch Converter for the Conductive Common Mode Noise Reduction(2555-08-05T04:58:32Z) Boonpirom NimitThis paper reduces system imbalance by replacing the single-switch converter with a synchronized double-switch converter based on two active switches technique and hybrid balance technique, including active balance and passive balance for common mode noise reduction. The system balance is experimentally evaluated by the common mode rejection ratio (CMRR). Finally, examples show that the CMRR of the single-switch converter is improved from 1.67 dB to 32.04 dB when the double-converter with two active switches technique is applied and to 41.5 dB when the double-switch converter with hybrid balance technique is applied.รายการ A Study on the System Imbalance of the Single-Switch Converter for the Conductive Common Mode Noise Reduction(IEICE TRANSACTIONS on Communications (Japan), 2550-08-01) Boonpirom NimitThis paper reduces system imbalance by replacing the single-switch converter with a synchronized double-switch converter based on two active switches technique and hybrid balance technique, including active balance and passive balance for common mode noise reduction.
