Hi, The circuit is working with a resistive load.
1. The mosfet source is connect to the high side of the load. The mosfet is a IRF510.
2. A IR2117 with bootstrap is being used and is referenced to Vs so the bootstrap capacitor voltage can be charged high enough to turn on the mosfet.
3. A 555 timer is used to control the IR2117 @ 10kHz with a 20 % duty cycle with a Vcc of 12 volts.
4. A permanent magnet alternator is used to supply Vin and can range from 0 to over 200 volts depending on the permanent magnet alternators RPM.
5. A bench power supply is used to supply power to the IC’s. This will be changed later.
The problem is :
When the resistive load is replace with a 12 volt battery the circuit does not work.
I do not understand why the circuit will work for a resistive load and not with a 12 battery as a load. Any suggestion will be greatly appreciated.
