Abstract
The Class E inverter is the basis for a low-cost high-frequency
ballast, but the control system is more complex than the
self-oscillating Class D inverter. The added complexity neutralizes any
cost savings gained by the single switch inverter. This paper explores a
novel self-oscillating Class E ballast from a design perspective. A
qualitative analysis shows how this self-oscillating system operates,
from startup, through ignition to the steady state. Optimum component
values are found from a quantitative analysis of the inverter. This
mathematical model is the basis for the design methodology. Analytical
results are compared with the physical model
