Title (EN) POWER SUPPLY DEVICE AND POWER SUPPLY METHOD
(FR) DISPOSITIF ET PROCEDE D'ALIMENTATION
(JA) 電力供給装置及び電力供給方法
Abstract: front page image
(EN)When amplifying an RF signal for power supply or a pulse signal for data transmission, amplification is performed so that the peak power of the RF signal is greater than the peak power of the pulse signal. Thus, it is possible to charge a capacitor (23) of a non-contact type radio communication device (2) by transmitting the RF signal having a large peak power even when the distance to the non-contact type radio communication device (2) is large.
(FR)Selon l'invention, lors de l'amplification d'un signal RF d'alimentation ou d'un signal à impulsions de transmission de données, on effectue l'amplification de telle manière que la puissance de crête du signal RF est supérieure à la puissance de crête du signal à impulsions. On peut dès lors charger un condensateur (23) d'un dispositif de communication radio du type sans contact (2) en transmettant le signal RF avec une puissance de crête élevée même lorsque le dispositif de communication radio du type sans contact (2) se trouve à une grande distance.
(JA) 電力供給用のRF信号、または、データ送信用のパルス信号を増幅する際、そのRF信号のピーク電力がパルス信号のピーク電力より大きくなるように増幅する。これにより、非接触型無線通信機器2までの距離が長くても、ピーク電力が大きいRF信号を送信することによって、非接触型無線通信機器2のコンデンサ23を充電することができる。
