Referring to fig. 3, a circuit diagram of a main circuit 1 of a conventional relatively common power source LWT2005 of a computer is shown, in which a remote switch module 31 is connected in parallel with a PS signal input terminal.

After a microcomputer of a conventional LWT2005 circuit is powered on, a PS signal sent by a main board controls the voltage of a 4 th pin (pulse width modulation control end) of an IC2, when the microcomputer is in a standby state, an electronic switch of a main board starting control circuit is turned off, the PS signal outputs a high level of 3.6V, the high level reaches a 6 th pin (starting end) of an IC1 (voltage comparison amplifier LM 339N) through R37, C35 is charged through a 3 rd pin of the IC1 from the inside, meanwhile, a 2 nd pin of an IC1 sends a comparison voltage to a 4 th pin of the IC2 through R41, the voltage of the 4 th pin of an IC2 is gradually increased from zero potential, and when the increased voltage exceeds 3V, the modulation pulse width voltage output of 8 th and 11 th pins of the IC2 is blocked, so that T2 pushes a transformer and a T1 main power supply switch transformer to stop supplying output voltages of +3.3V, ± 5V, 12V and the power supply is in a standby state. After the controlled start, the PS signal is grounded by the electronic switch of the motherboard start control circuit, the 6 th pin of the IC1 is at low level (0V), the 4 th pin of the IC2 is changed to low level (0V), and at this time, the 8 th and 11 th pins are allowed to output the pwm signal. The 13 th pin (output mode control end) of the IC2 is connected with a stabilized voltage +5V (the +5V voltage is output by the stabilized voltage in the IC 2), the pulse width modulator is in parallel push-pull type output, the 8 th pin and the 11 th pin output pulse width modulation signals with the phase difference of 180 degrees, the output frequency is half of the oscillation frequency of the externally-connected timing resistance-capacitance elements R30 and C30 of the 5 th pin and the 6 th pin of the IC2, and the excitation oscillation of the secondary winding of the T2 connected with the C poles of the triodes Q3 and Q4 is controlled and pushed.
