Which can limit the maximum output current on receiving device, have limitation supply current.
The transmitter unit of above-mentioned transmitting equipment is referred to as the half-bridge control ZCS (Zero of wireless power transmitting
Current Switch, Zero Current Switch) module, it has been internally integrated synclator, PWM automatic adjusuments, transmitting coil peak
The advantages that value current detecting, transmitting coil peak point current current limliting, integrated level is high, peripheral component is few, efficient, debugging is simple.
In general, the transmitting equipment is debugged, the circuit with reference to shown in figure 9, debugging step is such as before input adapts to
Under：
Step (1) is transferred to VR2 potentiometers minimum (crura intermedium voltage is minimum), the 23rd foot of U4 short circuit over the ground, the 6th foot
Connection+5V, oscillograph isolation probe are connected to the poles G of IGBT.
VR2 potentiometers are slowly tuned up (crura intermedium voltage), seen simultaneously by step (2), device power under no-load condition
Examine input power；If input power in 20W hereinafter, continue slowly tune up VR2, stop when input power reaches 20W or so
Potentiometer is adjusted, the frequency of the drive waveforms of IGBT can be observed with oscillograph at this time and writes down present resonant frequency, the drive of IGBT
The current waveform of dynamic waveform and transmitting coil is as shown in Figure 10.
Step (3), is adjusted to the frequency of oscillation of receiving coil and resonant capacitance identical as the working frequency of transmitter, connects
Upper load calculates transfer efficiency, adjusts resonant capacitance；When transfer efficiency highest, the humorous of resonant frequency and tranmitting frequency is received
It is good to shake.
Step (4), then VR2 is adjusted, allow output current and power to reach required value, so far power section debugging is completed；
Step (5) disconnects 23 feet of U4 and 6 foot shorting stubs and restores, powers on；After the power is turned on, transmitter is being waited for by MCU controls
Machine state (stand-by power consumption 5W or so), then receiving coil is put, it is communicated between transmitter and receiver successfully, transmitter power
Gradually change from small to big, until reaching maximum power, after battery, which fills, satisfies, receiver detects that filling full signal is notified that transmitter stops
It only works, into standby mode.
In debugging process, R45, the position of R46 adjustable current zero crossings, the big IGBT drive waveforms of resistance value can shift to an earlier date,
The small IGBT drivings wave delay of resistance value, as shown in waveform in Fig. 6, drive waveforms are ended in current zero-crossing point.It must be VR2 before debugging
Potentiometer is transferred to minimum (crura intermedium voltage is minimum), then again from small past big fine tuning；When putting receiver debugging, it is necessary to connecing
The resonant capacitance of receipts machine is adjusted to efficiency highest, can just tune up transmission power.
