Abstract:
A high frequency, high power factor inverter circuit for generating a current for a load, the inverter circuit comprising:A first inductor connected to receive an input voltage; a second inductor connected at one end to the load, and at a second end to a first node, the second inductor further being connected to the first inductor to act in combination as a voltage step-up auto-transformer which increases the input voltage; a first capacitive network connected in parallel across the load and the second inductor; a second capacitive network connected in series with the load, the second capacitive network having a capacitive value larger than the first capacitive network, wherein prior to the load being activated the first capacitive network and the load are operationally in parallel with each other, and the first capacitive network and the first inductor are in series with each other and, when the load is activated the second capacitive network, the load, and the first inductor are operationally in series with each other.
