Abstract:
1. An inverter for providing power to a load, the inverter comprising: a pulse start component operable to receive a first input indicative of a primary current, the pulse start component generating a first output responsive to a zero crossing of the first input; a pulse duration component operable to receive a second input indicative of a load current and a third input indicative of a direct current (DC) input voltage, the pulse duration component being operable to generate a second output responsive to the second and third inputs; a time delay component operable to receive the first output and the DC input voltage, the time delay component introducing a time delay to generate a delayed first output; a logic component operable to receive the delayed first output and the second output to generate a plurality of control signals; a plurality of switches operable to convert the DC input to the primary current in response to receiving the plurality of control signals; and a filtering component operable to filter the primary current for generating the load current.
