Abstract: A protection circuit applied to a convertor including M pieces of driving switch modules each coupled to a power source, a load and one of M sets of driving signals. The ith driving switch module is controlled by the ith set of driving signals to selectively enable current paths between the power source and the load. A first sub protection circuit in the protection circuit includes a first protection switch module and a first detection module coupled to the first protection switch module. When the ith set of driving signals indicates an error event, the first protection switch module selectively couples the ith set of driving signals to a reference voltage according to a first detection signal. M and i are positive integers, and i is not larger than M.

Abstract: An output power adjusting method is applied on an inverter. The inverter includes a capacitor to store direct current (DC) electricity provided by a photovoltaic (PV) module. At least the DC electricity provided by the PV module is converted into alternating current (AC) electricity. Determine whether a power value of the AC electricity exceeds a power threshold. When the AC electricity exceeds the power threshold, the inverter works in a continuous mode. When the AC electricity does not exceed the power threshold, the inverter works in a discontinuous mode where the PV module charges the capacitor. In the discontinuous mode, determine whether a voltage on the capacitor exceeds a reference voltage, and when the voltage on the capacitor exceeds the reference voltage, the DC electricity provided by the PV module and DC electricity in pulses provided by the capacitor are converted to the AC electricity.

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.
