<p>A compact induction heating system for use on an internal combustion engine (10) driven implement having an engine driven alternator (20) to generate DC current for storage in a battery (30) used as a source of clean DC current of less than 50 volts for ignition of fuel in the engine (10), the system comprises a high frequency inverter (40) with an input connected to the clean DC current source, a first current conductive path including a first capacitor (122) and a first switch (150a), a second current conductive path including a second capacitor (124) and a second switch (152a), a single load inductor (50) in both of the paths with DC current flowing in a first direction through the inductor (50) when the first switch (150a) is closed and in a second opposite direction through the inductor (50) when the second switch (152a) is closed and a gating circuit (140) to alternately close the switches at a driven frequency to control heating by the load inductor (50).</p> |
