Problems solved by technology

However, if figure 2 As shown in the waveform W2_2 of , during the modulation period (that is, when the gate signals of the switch components A6 and B6 are at high potential), the gate of the lower bridge switch component B2 still has a residual voltage, which cannot completely reach zero potential, causing the lower bridge switch component B2 cannot be completely disconnected, causing unnecessary power consumption during modulation

Abstract

A signal modulation method for a receiving-end module of an induction type power supply system includes configuring a plurality of modulation periods corresponding to a modulation signal; performing modulation on a first terminal of an induction coil of the receiving-end module during the i<SP>th< / SP>modulation period among the plurality of modulation periods, wherein i is an odd number; and performing modulation on a second terminal of the induction coil of the receiving-end module during the j<SP>th< / SP>modulation period among the plurality of modulation periods, wherein j is an even number; wherein the second terminal does not undergo modulation when the first terminal is being modulated, and the first terminal does not undergo modulation when the second terminal is being modulated. The present invention also provides a signal rectification and modulation device.

Description

technical field [0001] The invention relates to a signal modulation method and a signal rectification and modulation device, in particular to a staggered signal modulation method and a signal rectification and modulation device. Background technique [0002] In the inductive power supply, in order to operate safely, it is necessary to confirm that the induction area on the power supply coil is the correct power receiving device at the supply end, and only transmit power when the power can be received. In order for the power supply end to identify the power receiving device Whether the terminal is a correct power receiving device needs to be identified by transmitting a data code. The transmission of the data code is to drive the power supply coil to generate resonance through the power supply end, and transmit the electromagnetic energy to the power receiving end for power transmission. When the power receiving end receives power, the impedance state on the receiving coil ca...
