F.N. 43870 CAN 1A Abstract of the Disclosure An amplifier which has special application as an induction coil driver. A multi-frequency signal is used to modulate the pulse width of a square wave, resulting in a pulse modulated signal. The pulse modulated signal is divided into two delay signals. The falling edge of each pulse is delayed in one of the delay signals, while the rising edge of each pulse is delayed in the other delay signal. This creates a "dead band" between the two signals for each pulse. The signals are used to drive two metal oxide semiconducting field-effect transistors, which are connected to positive and negative power supplies. The switching of the MOSFETs occurs during the dead band which, when combined with a novel inductor-diode circuit, results in high-efficiency power transfer. The amplified modulated signal is then subjected to a low-pass filter which cancels out the square wave carrier and switching noise. The amplified analog signal may then be applied to a non-tuned induction coil.
