Dead time of > 10µs would be required in order to prevent a inverter-leg from being arm-short. It depends on the optocoupler’s characteristics. In this board, a slow and low-cost type of optocoupler is selected. 2. Two isolated power supplies are required. For the primary side: +5V for CPU operation. For the secondary side: +15V for SPM operation. +5V is generated by the use of the voltage regulator of7805 Primary 5V C24 100uF 16V 10kΩ 1/8W ©2003 Fairchild Semiconductor Corporation 1 2 3 4 5 6 7 8 9 Fo 5V 102 Fo 5V GND 10 Secondary 15V 1 2 3 4 5 6 7 8 9 Fault Primary 5V Secondary 15V REG1 7805 VIN VOUT CN1 GND 2 C22 104 1 3 U3 H11A817B Secondary 5V Primary GND Secondary 15V 10 GND C25 33uF 35V C21 104 1 2 COM COM 2 15V 15V 1 Primary GND Secondary GND Secondar 15V Secondary GND U9 Dip-SPM (22) V B(W ) (21) V CC(W H) P (32) U2 H11A817B Secondary GND Secondar 5V R9 20 1/4W VB VCC CO M IN VS OUT D3 1N4937 P W (31) P W W 2 U1 H11A817B R3 560 1/8W C16 104 C14 33uF 35V (20) IN (WH ) (23) V S(W ) (18) V B(V) (17) V CC(VH) C13 104 Secondar 5V R8 20 1/4W VB VCC CO M IN D2 1N4937 C3 122 U8 H11A817B R2 560 1/8W C17 104 (15) IN (VH) (19) V S(V) (13) V B(U) (12) V CC(UH) R12 270 1/8W C8 104 (16) C OM (H) OUT VS V (30) C2 122 R4 20 1/4W D1 1N4937 C9 33uF 35V V VB VCC CO M OUT C20 0.1uF 630V IN VS U (29) V M V dc U7 H11A817B R1 560 1/8W C18 104 C6 104 R11 56 1/8W R10 3.9K 1/8W R5 560 1/8W R6 560 1/8W R7 560 1/8W C19 102 R48 390 1/8W C7 33uF 35V C1 122 (11) IN (UH) (14) V S(U) U (10) R SC (9) C SC (8) C FOD U C(SC) C(FOD) (7) V FO Secondar 5V U6 H11A817B OUT(WL) N W ( 28) C15 333 (6) C OM (L) (5) IN (WL ) (4) IN (VL) VFO IN(W L) IN(VL) (3) IN (UL) (2) C OM (L) (1) V CC(L) OUT(VL) IN(UL) CO M(L) VCC OUT(UL) U5 H11A817B C10 471 C11 471 C12 471 C23 102 N V ( 27) N N U ( 26) N Rev.
