Abstract
A control method for a DC to AC converter, selectively operating in a continuous conduction mode and a discontinuous conduction mode is disclosed. In the discontinuous conduction mode, the DC to AC converter outputs a first output signal having a first work frequency according to a power value of an input signal. The first work frequency relates to a plurality of first cycles. A first transition period and a first standby period in each first cycle have a first time ratio therebetween. Determine a power value of the first output signal produced during the first transition period. When the power value of the first output signal increases, the first work frequency is increased. When the power value of the first output signal decreases, the first work frequency is decreased.
